This weekend, Andrej Karpathy, the former director of AI at Tesla and a founding member of OpenAI, decided he wanted to read a book. But he did not want to read it alone. He wanted to read it accompanied by a committee of artificial intelligences, each offering its own perspective, critiquing the others, and eventually synthesizing a final answer under the guidance of a "Chairman." To make this happen, Karpathy wrote what he called a "vibe code project" — a piece of software written quickly, largely by AI assistants, intended for fun rather than function. He posted the result, a repository called "LLM Council," to GitHub with a stark disclaimer: "I’m not going to support it in any way... Code is ephemeral now and libraries are over." Yet, for technical decision-makers across the enterpris…

It's not just Google's Gemini 3, Nano Banana Pro, and Anthropic's Claude Opus 4.5 we have to be thankful for this year around the Thanksgiving holiday here in the U.S. No, today the German AI startup Black Forest Labs released FLUX.2, a new image generation and editing system complete with four different models designed to support production-grade creative workflows. FLUX.2 introduces multi-reference conditioning, higher-fidelity outputs, and improved text rendering, and it expands the company’s open-core ecosystem with both commercial endpoints and open-weight checkpoints. While Black Forest Labs previously launched with and made a name for itself on open source text-to-image models in its Flux family, today's release includes one fully open-source component: the Flux.2 VAE, available no…

Introduction Let's dive into the core components that form the backbone of Azure. 1. Regions and Availability Zones: Global Reach, Local Resilience Imagine a global network of interconnected data centers. That's essentially what Azure provides, organized into Regions and Availability Zones. Azure Regions: A region is a geographical area that contains one or more data centers. Think of them as massive, independent data center hubs located across the globe (e.g., "East US," "West Europe," "Southeast Asia"). Choosing the right region is crucial for data residency, compliance, and minimizing latency for your users. Availability Zones (AZs): Within many Azure Regions, you'll find Availability Zones. These are physically separate locations within an Azure region, each with independent power, coo…  ( 8 min )

Most UI tests today still look like this: you code the steps, you hard-code selectors (IDs, XPath, CSS), you pray they don’t break on the next release. This works… until: the accessibility tree is a mess, the app runs inside a WebView, the UI is legacy or hybrid, or there is no reliable locator at all. At that point, traditional automation just gives up. I’ve been working on a different approach: Instead of hard-coding selectors and steps, let an AI agent build the locator and the action at runtime. This is what our project, AI Agent, is about. 🚀 AI Agent is open source & early-stage. If this resonates with you, please ⭐ star the repo: 👉 https://github.com/aidriventesting/Agent It helps a lot with visibility and future sponsorship.

In September 2025, the Intergenerational Open Geospatial Carbon Registry (OGCR) was officially launched under the funding of Horizon Europe, marking a major step forward in the creation of an open, transparent, and scientifically robust framework for carbon accounting across the EU. The initiative brings together more than thirty partners, including universities, research institutes, SMEs and NGOs, and aims to run through 2029, with an investment of €11.5 million. The project’s ambition is broad: to offer Europe’s 9.1 million farmers and forest managers simple, affordable tools to measure, verify, and certify carbon sequestration and ecosystem-service benefits from their land-management practices. At the heart of OGCR’s innovation is the creation of harmonized, updateable baseline data on soil carbon along with biomass and peat carbon. These geospatial carbon baselines, scalable from local to pan-European level, are intended to underpin fair, transparent certification and remuneration under the upcoming framework of Carbon Removals Certification Framework (CRCF).

As Flutter developers, we've all been there. Your app crashes in production, users abandon it, and you don't find out until the 1-star reviews start rolling in. Traditional crash analytics tools are great, but they come with their own problems: complex setup, vendor lock-in, privacy concerns, and that dreaded delay before you actually see what went wrong. What if you could get crash reports instantly, exactly where your team already communicates? Don't get me wrong — tools like Firebase Crashlytics and Sentry are powerful. But they have downsides: Delayed notifications: You often learn about crashes hours later Context switching: Checking another dashboard breaks your flow Privacy concerns: Sensitive data going to third-party servers Overkill for small teams: Full-featured analytics when y…  ( 9 min )

Microsoft’s Xbox Series S is the breakout star of Black Friday 2025. The compact console is selling for a compelling $349 at major retailers. This price makes it the most affordable gateway into the current generation of gaming. The deal is available now through the holiday shopping weekend. 🔴👉 https://tinyurl.com/y4szx7ju Xbox Series S Black Friday Gamers are flocking to this offer for its unmatched value. According to Reuters, early sales data shows a significant spike in Xbox Series S transactions. This trend highlights a strong consumer shift toward budget-conscious entertainment. Why The $349 Price Point Is a Game-Changer Its integration with Xbox Game Pass is the killer feature. Subscribers get immediate access to a vast library of games. This combination of affordable hardware and a rich software library presents a complete, low-cost ecosystem. Breaking Down The Console’s Capabilities The main compromise is its digital-only nature. There is no disc drive for physical media. This makes a stable internet connection essential for downloading games and updates. Market Impact and Consumer Choice The long-term effect benefits the entire Xbox ecosystem. More consoles in homes drive Game Pass subscriptions and digital game sales. This creates a recurring revenue model for Microsoft that extends beyond the initial hardware sale. The Xbox Series S at $349 is a near-perfect Black Friday deal for anyone entering the current console generation.  ( 6 min )

One wrong API endpoint in production can cost you users and revenue instantly. Shipping code that accidentally points to a test database—or worse, hits live data with test parameters—is a developer's nightmare. You need distinct boundaries. Managing these boundaries using multiple environments is the standard for 2025 web development. It keeps your development fast, your staging safe, and your production secure. This guide explains how to handle multiple environments in React, covering the modern transition to Vite, maintaining legacy Create React App projects, and managing Dockerized deployments. Most professional teams work across at least three stages: Development, Staging (QA), and Production. Each needs its own set of rules. Hardcoding these values is fragile and dangerous.

In the modern digital landscape, businesses are increasingly relying on software-as-a-service (SaaS) solutions to drive efficiency, deliver better customer experiences, and scale operations. While off-the-shelf software can be a quick fix, it often falls short when a business has unique processes, specialized requirements, or plans for rapid growth. This is where custom SaaS development comes into play, offering businesses a tailored solution that adapts perfectly to their needs. Software Development Hub (SDH) specializes in building custom SaaS platforms that are designed to scale, save costs, provide full customization, remain future-proof, and accelerate time-to-market.

Most crypto trading still relies on centralized systems; fast, yes, but fragile. A decentralized exchange flips that model entirely. With trustless execution, transparent mechanics, and user-owned assets, developers finally get a foundation that’s predictable, verifiable, and free from middlemen. That’s the direction we’re taking with Haveto: True ownership → no third-party custody Peer-to-peer trading → secure by design Transparent execution → every interaction verifiable on-chain High throughput → smart sharding keeps performance smooth For anyone exploring decentralized infrastructure or designing trading experiences that don’t depend on centralized control, this is a space worth paying close attention to.

Spring is paradoxical. It “solves” problems it created — and trained a generation of developers to understand Spring, not software engineering. Dependency Injection everywhere (even when there’s 1 implementation). Interfaces for everything (even when there’s 1 implementation). Annotations as the new programming language. And @Transactional as a magical forcefield masking the fact that no one understands what should actually be atomic. JDBC? SQL? DB design? Transaction boundaries? Most Spring shops never touch them directly — they let the framework decide. The result: the classic Enterprise Java Happy Meal.

Multitenancy in Yii2: Practical Guide and Code Examples Multitenancy is a powerful architectural pattern that allows a single application instance to serve multiple tenants (clients or organizations), keeping their data isolated. Yii2, being a flexible PHP framework, can be adapted for multitenant applications in several ways. In this article, I'll show you how to implement a basic multitenant setup in Yii2, including code snippets and best practices. Single Database, Shared Schema: All tenants share the same tables, with a tenant_id column to separate data. Single Database, Separate Schemas: Each tenant has its own set of tables (schema).

Last week, I spent over two hours helping a client build an AI-powered chatbot for their wellness e-commerce site. I set up a sophisticated RAG system using Cloudflare Vectorize, wrote custom vectorization scripts, and carefully configured Workers AI bindings. The client was pleased with the work.

AI-assisted coding has been evolving fast, but until now, it often felt like a patchwork solution. You ask for a snippet, get a block of code, and try to fit it into your project. Sometimes it worked. Sometimes it broke everything. Enter Google Antigravity—a shift that changes how AI integrates with development workflows. Breaking Work into Smaller, Manageable Parts One of the biggest hurdles with AI coding has been context. Traditional AI tools are great at generating code snippets but struggle to understand the flow of your project. Antigravity tackles this by connecting directly to your editor and understanding the full codebase. This means it can: Run commands in your terminal automatically Install dependencies on its own Build and place components in the correct folder Test frontend features in a browser and fix issues on the spot This is more than autocomplete. It’s collaboration at a new level. Towards Enterprise-Grade AI Development Antigravity feels like the first step toward full enterprise AI tools. Imagine: Shared workspaces for your team Project-level memory that remembers context across sessions Secure team access and version history Real workflow integration instead of isolated AI snippets AI is no longer just assisting—it’s becoming part of the development workflow, capable of handling real projects end-to-end. What This Means for Developers This approach promises cleaner components, easier debugging, and a smoother workflow. It’s a vision of AI as a true partner in coding, not just a code generator. I’m excited to see how far this can go. Could we soon have AI tools that function like a full teammate, understanding projects, maintaining context, and supporting real development just like enterprise software does today? What do you think? Could this change the way we code professionally?  ( 7 min )

One of the most useful patterns in software development — and one that is available in many languages, not just Swift — is dependency injection. When I first learned about it over a decade ago, I started using it everywhere possible. It’s a simple idea with a surprisingly big impact. Here’s why it’s worth mastering. One of the biggest advantages of using dependency injection is that it makes our code immediately more testable. Even in projects full of singletons, we can break apart large chunks of tightly coupled code into smaller, more loosely coupled components. Our implementations rely more on protocols (interfaces) rather than concrete classes, making it easier to swap or replace them. By depending on abstractions rather than concrete implementations, each component can focus solely on…  ( 10 min )

Modern CSS is nothing short of incredible. It gives us the tools to craft rich, interactive, and visually stunning experiences on the web. But with this surge in capability comes a new weakness—not in CSS itself, but in the way we work with it. When I started my career as a web developer, writing CSS often meant inventing hacks to work around what it couldn’t do. Those days are far behind us. Today, CSS offers advanced layout systems, 3D transformations, and highly flexible animation tools. Yet most of the challenges we face in modern CSS aren’t about missing features—they stem from how we author it. This is why the future of CSS might not live in plain text files at all, but in visual creation tools. That idea might sound outrageous at first, but bear with me—I’ll try to make the case.

So on Nov 3rd, after months of feeling completely lost about what I want to do in the future, I finally decided on my path. That path is DEBMO. It originally started as something much smaller, called Project-DB, a drag-and-drop (DnD) query tool that would let tech and non-tech people work with databases without hassle. The idea was to connect multiple databases (MariaDB, PostgreSQL, even Snowflake warehouses), run queries, and process data in one place. After I met the two people who later joined me on this journey, we realized it needed to be more than “just” a query tool. That’s when we came up with things like Excelerator, Data Studio, and a more advanced permissions system to support the way teams actually work with data together. Right now, I’m the only one working on the development side. There have already been a lot of sleepless nights going into this, and I don’t regret even 0.1% of it. So far, we’ve built: The main project structure Connections to Buckets / DB / Redis Login with 2FA Role-based permissions The Admin Portal It’s tiring and hard, but it’s also exciting to see it slowly become real. Our current goal is to have a free testing phase starting around Jan/Feb, where anyone can try the MVP for a few months. During that time we’ll collect feedback, fix bugs, and ship the features we still have planned. The MVP will stay free during this testing period before we eventually move to paid plans later on. If you’re interested in the project, want to follow the development, or give feedback before and during the testing launch, you can join the DEBMO Discord server (link below). Until then, I’ll be posting weekly devlogs here on dev.to to share progress, decisions, and struggles along the way. Wish me luck on this journey. 🚀 Link: https://discord.gg/zJC8tU2y  ( 7 min )

The debate between Serverless vs Containers has never been more relevant, and 2026 is the first year where the winning pattern is finally visible. According to recent Cloud Native and FinOps surveys, more than 78% of engineering teams now run hybrid architectures, combining both Serverless and Containers to optimize cost, performance, and development velocity. The truth is clear: Serverless now powers millions of event-driven workloads with almost zero operational overhead. Containers remain the backbone for long-running, stateful, and AI-driven applications. Cloud providers now offer serverless containers, blurring the line between both models. This blog is written for **startup CTOs, infra engineers, cloud architects, DevOps teams, FinOps teams, and digital product engineering co…  ( 10 min )

Artificial Intelligence has revolutionised lives in the past few years. We’ve moved from simple chatbots and prediction tools to a new kind of smart system—AI agents. These agents don’t just respond to questions. They can think, plan, and take action on their own. They can talk to people, use software tools, and even work with other agents to reach goals. But what makes all this possible is something most people don’t see: AI agent frameworks. These frameworks are the hidden structure that helps build, run, and manage AI agents. They are what turn language models into full digital workers. Let’s discuss them in detail. At its essence, an artificial intelligence agent is a kind of software that can sense its surroundings, formulate objectives, and then act in a way to accomplish those objec…  ( 13 min )

TypeScript's type system is a powerful tool for building robust applications. Features like utility types and interface inheritance feel like natural ways to reduce repetition and structure code. However, when overused, they can silently introduce complexity and fragility that undermine the very maintainability we seek. Utility types like Pick, Omit, and Partial are incredibly convenient. They allow us to create new types on the fly, often saving us from writing verbose type definitions. The Problem: Overusing them, especially nested within other utilities, creates "type opaqueness." The origin and contract of a type become obscured, making the code harder to understand and reason about. Consider this example: type User = { id: string; name: string; email: string; createdAt: Date; …  ( 8 min )

Overview HashMap is a widely-used data structure in Java that implements the Map interface for storing key-value pairs. It delivers O(1) time complexity for fundamental operations like insertion and retrieval under typical conditions. HashMap utilizes an array of nodes as its foundation, commonly referred to as the bucket array. Each bucket can accommodate multiple entries through either a linked list or tree structure when collisions occur. Every entry in the HashMap is represented by a Node object that implements the Map.Entry interface: static class Node implements Map.Entry { final int hash; // Hash code of the key final K key; // The key V value; // Associated value Node next; // Reference to next node } Hash Computatio…  ( 8 min )

When I first tried installing GNS3 on Fedora, I checked the official GNS3 website — and surprisingly, Fedora wasn’t listed. They only provide installation guides for: Ubuntu-based distros Debian-based distros Arch-based distros But no Fedora 😅 Luckily, GNS3 is actually available on Fedora — directly from its official repositories. Here’s how you can install it and run your very first “Hello, World!” inside GNS3! Even though Fedora isn't listed on the official website, Fedora includes GNS3 in its own package repositories. sudo dnf install gns3-server gns3-gui This gives you: gns3-server → backend gns3-gui → the graphical application When launching GNS3 for the first time, the setup wizard appears.

Turbocharge Your LLMs: A Breakthrough in Neural Network Optimization Stuck in slow training cycles? Watch your neural networks grind to a halt, especially with massive language models? Model training can feel like navigating a minefield of instability and frustratingly slow progress. But what if you could sidestep these common pitfalls and unlock significantly faster, more reliable training? The key lies in a new approach to gradient optimization, specifically designed for the complexities of modern neural networks. Imagine a team of rowers – if their strokes are perfectly synchronized (orthogonalized), the boat moves faster and more efficiently. Similarly, by carefully orthogonalizing gradient updates, we can drastically improve convergence speed during training. This novel optimizer em…  ( 7 min )

Hey Dev.To community! 👋 I've just launched a new open-source project that might be of interest to those building CI/CD pipelines or managing internal security tooling: Ephemeral Vulnerability Scanner. This is a 100% client-side application built with vanilla JS/HTML/CSS. You clone it, open index.html, upload your system inventory (inventory.json), and get an instant, privacy-safe vulnerability report. 💡 Why this architecture? It addresses the privacy concern: No sensitive system data leaves your device. It's fast and eliminates backend maintenance overhead. It's transparent: you can literally inspect the app.js source to see the entire logic. Under the Hood: We use platform-specific commands (PowerShell, dpkg, rpm, brew) to generate the initial JSON inventory. The analysis logic hits MSRC CSAF API (Windows), OSV.dev API (Open Source), and CISA KEV for a strict, verified lookup. Results are grouped into clean, actionable "Package Cards" with the minimum safe version calculated automatically. Check out the repo, try the demo, and let me know what you think of the client-side approach for security analysis! 🔗 Live Demo: VulnScan  ( 6 min )

Body: I’ve been building a lot of AI agents lately. The logic is usually fun to write, but I kept hitting the same wall: State Management. LLMs are stateless. As soon as the session ends, the context is gone. Sure, you can pass the chat history, but once that hits the token limit, your agent gets amnesia. The standard solution is "Just use a Vector Database." But setting up a dedicated Pinecone or Weaviate instance, configuring the embedding pipeline (OpenAI/HuggingFace), and writing the chunking logic just to store a few user preferences felt like massive overkill for my side projects. I didn't want to manage infrastructure; I just wanted my agent to remember that my favorite color is blue. So, I spent the last few weeks building a dedicated API to abstract all that boring stuff away. It’…  ( 8 min )

Most engineering teams assume scaling requires adding more: More tools More dashboards More AI More engineers But every experienced engineer eventually learns the truth: Systems don’t slow down because they lack tools. They slow down because of friction. Friction created by scattered data, noisy workflows, redundant SaaS tools, and “manual work disguised as process.” Engineering teams often operate across 15–25 tools. Individually useful. Collectively damaging. Tool sprawl creates: Fragmented data models Multiple “sources of truth” Delays in handoffs Duplicated workflows Hidden manual steps everywhere When each tool stores a different slice of truth, your architecture becomes diffuse, not distributed. 10x companies don’t scale by adding more layers.

JavaScript, by its nature, is a single-threaded language. This means it traditionally executes one operation at a time on the browser's "main thread." This main thread is responsible for everything a user sees and interacts with: rendering the UI, handling user input, running animations, and executing all your application's JavaScript. While this single-threaded model simplifies development in many ways, it presents a significant challenge: what happens when your JavaScript needs to perform a heavy, CPU-intensive task? The answer, historically, was a frozen UI, unresponsive buttons, and a frustrating user experience. Enter Web Workers. Web Workers provide a way to run JavaScript scripts in background threads, separate from the main execution thread of a web page. By offloading CPU-intensiv…  ( 12 min )

Most companies still treat privacy as a policy problem. That difference — between writing rules and enforcing them — is what separates organizations that talk about responsible data use from those that actually achieve it. The Weekly Translation Failure Every week, legal, product, and engineering teams sit down to align on privacy and responsible data use. And every week, they run into the same challenge: It’s not a communication problem. A privacy policy that reads cleanly in a spec document becomes a maze of implementation questions the moment it meets code: Policy teams speak in rights, obligations, and business rules. The result? The Missing Layer: A Shared Operational Foundation What’s missing isn’t collaboration — it’s a common operational foundation. This is why privacy must be treated as a systems problem. That’s the core principle behind emerging privacy infrastructure — where legal definitions, business policies, and data models converge into a single executable framework. When obligations are expressed as code, they become: When Policy Lives in Infrastructure When privacy is embedded directly in infrastructure, the dynamic between teams changes entirely: That’s not just better governance — it’s a better growth model. Instead of being boxed in by complexity, teams gain the freedom to innovate safely with sensitive data — whether it’s for AI, analytics, personalization, or compliance. Privacy as a Competitive Advantage Enterprises that get this right stop playing defense with privacy. Because when privacy becomes part of your stack, not just your policy binder, you don’t just comply. You scale responsibly. You innovate with confidence. And you turn privacy from a blocker into a feature of your growth model.  ( 7 min )

What is a CDN? A Content Delivery Network (CDN) is a strategically distributed system of servers designed to deliver internet content with maximum speed and efficiency to users worldwide. According to recent industry data, over 80% of global web traffic now flows through CDN infrastructure, making it an essential component of modern digital infrastructure. When a user accesses a website, the CDN intelligently delivers content from the server geographically closest to that user—known as an "edge server" or "Point of Presence" (PoP)—rather than routing all requests to a single origin server. This distributed architecture fundamentally transforms how content reaches end users, reducing latency by up to 50 milliseconds for 95% of internet users globally. 1.

Observables This article aims to explain how observables help or fit in into the use case of sharing data among views. Before that, we need some context. When we want to share data among views, we usually use classes instead of structs. The main reason is that whenever we use structs, each view will have its own copy of said struct, so it does not really fit the use case if you would like to share data among views. To be able to share data among views, you need to use classes. import Combine class Counter: ObservableObject { @Published var count = 0 } The above code contains a class called Counter and it inherits ObservableObject. SwiftUI makes use of the subscriber-publisher model. In this case, the Counter class publishes the count variable. struct ContentView: View { @State…  ( 7 min )

Arrays in JavaScript are like tiny storage shelves where each item has a number tag (index). They let us store multiple values together and work with them easily. What Are Arrays? An array is a collection of elements. Arrays are represented using square brackets [], like this: let arr = [4, 8, 7, -1, 0, 4, 9]; Indexing in Arrays So for an array of n elements, the valid index range is: Examples: console.log(arr[2]); // 7 console.log(arr[25]); // undefined Array Length console.log(arr.length); // 7 Arrays Are Mutable 1️⃣ push() let arr = [1, 2, 3]; arr.push(4, 5); console.log(arr); // [1, 2, 3, 4, 5] 2️⃣ pop() let arr = [1, 2, 3, 4, 5]; arr.pop(); console.log(arr); // [1, 2, 3, 4] 3️⃣ unshift() let arr = [1, 2, 3]; arr.unshift(4, 5); console.log(arr); // [4, 5, 1, 2, 3] 4️⃣ shift() let arr = [1, 2, 3]; arr.shift(); console.log(arr); // [2, 3] 5️⃣ splice() A powerful method used to add, remove, or replace elements. Examples: let arr = [5, 6, 7, 8, 9, 10, 11, 12]; arr.splice(3); // delete all from index 3 arr.splice(3, 1); // delete only element at index 3 arr.splice(3, 2, "raj", "shekhar", "john"); // replace 2 items Given: let friends = ["sheldon", "rachel", "ross", "chandler", "monica", "penny"]; 1️⃣ Remove "sheldon" and add "pheobe" friends.shift(); friends.unshift("pheobe"); 2️⃣ Remove "penny" and add "joey" friends.pop(); friends.push("joey"); 3️⃣ Add "emma" between "rachel" and "ross" friends.splice(2, 0, "emma");  ( 7 min )

Getting Inside a Running Container When your container is already running, you can access its shell using: docker exec -it bash If the container doesn't have Bash installed, try: docker exec -it sh This lets you debug, inspect logs, check files, or test configurations from inside the container. When Your Container Isn’t Running (or Exits Immediately) When a container won’t start, docker exec won’t work. docker run -it --entrypoint=/bin/bash This forces the container to start with a shell, even if its actual entrypoint fails. Tip: Useful Docker Compose Commands Stop services and remove containers + volumes docker compose -f down -v The -v flag removes volumes as well. Start services in detached (background) mode docker compose -f up -d The -d option keeps everything running in the background so you can continue working.  ( 6 min )

Gartner estimates that over 80% of data teams spend more time finding data than analyzing it, largely due to missing lineage, unclear ownership, and manual documentation. As organizations scale their data ecosystems, a robust automated data lineage solution becomes essential—not just for governance, but for analytics accuracy, regulatory compliance, and operational efficiency. Data lineage is no longer a “nice to have.” In modern enterprises with cloud warehouses, diverse data tools, and complex pipelines, manual lineage quickly becomes outdated and unreliable. Automation bridges this gap by continuously tracing data flows across systems, helping teams understand where data comes from, how it transforms, and where it goes.

Next.js 16 introduces a new file-convention: proxy.js / proxy.ts (often “Proxy”) which supersedes the older middleware.js. This feature allows you to intercept HTTP requests early (before routing/rendering) and run custom logic—redirects, rewrites, header manipulation, or forwarding (proxying) to another service. In e-commerce (or any frontend/back-end scenario) this gives you a powerful tool: you can make your Next.js app act as a Backend-for-Frontend (BFF) layer, hiding upstream APIs, consolidating micro-services, enforcing auth, caching, rewriting URLs, etc. This aligns well with many of the architectures discussed in your referenced articles about Next.js for commerce (SSG/ISR/SSR strategies etc).

They pause, open a new tab, and quietly type your thought—loosely translated—into an AI chat window. They’re not announcing it. They’re not making a point. They’re just… checking. They scan the answer, nod almost imperceptibly, and fold the result back into the conversation. No one reacts. No one debates whether this is allowed. The tool is background, like a calculator or a search bar. The revolution came quietly and nobody objected because it was useful. The silence here isn’t fear. It isn’t uncertainty. It’s acceptance—the kind of acceptance that happens when something crosses the line from “c…  ( 11 min )

I don’t code. But I spend my days around people who do — the late-night builders, the tab-vs-space philosophers, the “I’ll fix it in 5 minutes” liars (we all know it’s never 5 minutes :P). And being surrounded by them taught me something no self-help book ever has: Software updates constantly. And that… makes no sense. 💻 In tech, upgrades are NORMAL. Expected. Celebrated. If a framework updates every 3 weeks? If a library is deprecated? If you say “we’re rewriting everything”? If code breaks? But in life?

As developers, when we talk about “digitization,” we usually think of startups, enterprise systems, or e-commerce. But temples face the same kind of operational challenges that businesses do—sometimes even more complex because they serve large crowds in a very short time. This post explores, from a technical viewpoint, why Indian temples benefit from digital solutions and what kind of systems can help them run more smoothly. *1. Cashless Donations Are Now the New Normal The shift toward digital payments in India is massive. UPI is everywhere—from large stores to roadside tea stalls.

How do we make a Hello World in Rust?? If you prefer watching over reading, you can watch the video version of this bootcamp segment right here: The first thing you should do is install Rust. You should end up on a page that guides you through using rustup, which is an excellent tool for managing Rust versions. To verify your installation, type rustc --version in your terminal. Rust is a compiled programming language. rustc is the compiler, and cargo is the package manager. If you have both of these, you are good to go. We will start with a very simple "Hello, World!" because this step is very important to understand what happens behind the scenes. This approach uses rustc directly. This is something you usually don't see in tutorials, but it helps to understand what automated tools do for…  ( 7 min )

Hi everyone! I’m @nyaomaru, a frontend engineer who quietly moved to the Netherlands. 🇳🇱 If you write TypeScript, you’ve probably bumped into the term “variance” at some point: covariant contravariant invariant bivariant You may have a vague feeling of “I sorta get it… but not really.” Personally, I struggled especially with contravariance and bivariance — they’re really counter-intuitive. And when I tried to deep-read React’s type definitions, I ran into Flow’s variance annotations +T / -T and completely froze: export type Element = React$Element; export type RefSetter = React$RefSetter; “What are + and -!?” React using this in Flow!?” That was the entrance to understand variance for me. In this article, I’ll use both TypeScript and Flow to build a practical, real-world u…  ( 15 min )

Have you ever wanted to build a marketplace where users can buy and sell products using stablecoins without worrying about gas fees? In this article, I'll walk you through how I built Polygon x402 Marketplace, a gasless peer-to-peer marketplace using the x402 protocol on Polygon Amoy. Traditional blockchain marketplaces have a major UX problem: users need to hold native tokens (like MATIC) just to pay for gas fees. This creates friction because: New users need to acquire native tokens from exchanges first Users must manage multiple token balances Gas prices fluctuate, making transaction costs unpredictable The x402 protocol enables gasless USDC transfers by using EIP-712 signatures and a facilitator network. Users only need USDC in their wallet to participate in the marketplace - no native…  ( 8 min )

The Future Belongs to Those Who Talk to Machines, Not to Those Who Code Them 🧠 The Dawn of a New Era: Redefining Developer Power For many years, the quintessential symbol of technological influence was a lone programmer, their face bathed in the glow of endless lines of code. Possessing an innovative concept meant relying on them—they acted as the indispensable interpreter, architect, and steward of digital innovation. Without their profound grasp of machine languages, aspirations stayed firmly in the realm of imagination. However, this long-standing paradigm is now rapidly drawing to a close. Consider a future where the most sought-after capability isn't proficiency in Python, PHP, or JavaScript, but rather an exceptional command of... natural language.

Something weird happened while we were all busy optimizing for Google. Gen Z stopped using it. Not entirely, obviously. But here's the thing: 40% of young people now use TikTok or Instagram as their primary search engine. Not for everything, but for restaurants, product recommendations, how-to tutorials, and basically anything where they want real human opinions instead of SEO-optimized listicles from 2019. Google's own data confirmed this in 2024. Which must have been a fun meeting. So now TikTok isn't just a platform where people do dances and share life hacks. It's a legitimate search destination with its own ranking factors, optimization strategies, and yes—an algorithm you need to understand if you want anyone to actually find your content.

The future of AI agents relies on their ability to seamlessly and efficiently integrate with vast libraries of tools—from internal databases and company-specific APIs to public services like GitHub and Slack. As professional developers, we know that scaling an agent from five tools to fifty or five hundred introduces critical bottlenecks: context bloat, slow execution, and unpredictable tool invocation. To solve these challenges, we are excited to introduce three advanced features on the Claude Developer Platform that fundamentally change how agents discover, orchestrate, and utilize external capabilities. These features move Claude from simple sequential function calling to intelligent, programmatic orchestration. When building agents that connect to many services (e.g., a five-server MCP…  ( 9 min )

Decoding Movement: Emulating Biological Motion for Smarter Robots Ever watched a cat effortlessly navigate a complex environment and wondered how to program a robot to do the same? We're constantly striving to create robots with the agility and adaptability of animals, but the traditional approach of programming every joint movement is incredibly complex and often fails in unpredictable situations. What if robots could learn to move, not just follow pre-defined paths? This is where neuromechanical emulation comes in. The core idea is to build a virtual model of an animal's body, connect it to a simulated nervous system controlled by a neural network, and then train that system to reproduce real-world movements captured from motion capture data.

I originally posted this post on my blog a long time ago in a galaxy far, far away. If you want to start a coding blog, don't start with a deep dive of the Linux Kernel or other cryptic topics—unless you're an expert on those topics. TIL posts are shorter posts where you share something you've found or figured out. With TIL posts, you don't have to worry about long introductions or conclusions. Just write a good headline, a code block, a quick explanation, and your sources. And write using your own words, like in a conversation with a coworker. That's enough to make a post worth reading. Don't try to lecture the coding world about what they should do. Start documenting your learning instead. Instead of writing "5 VS Code extensions every coder should install," try "TIL: 5 VS Code extensions I couldn't avoid installing." Or instead of "5 Git commands every coder should know," covering the same basic Git commands every beginner writes about, write "TIL: 5 Git basic commands to use everyday" or "TIL: How Git Status works." Spent 20 minutes or more figuring out something? write a TIL post. That's the easiest way to start a coding blog. Apart from coding, writing has been one of the best skills I've developed as a coder. It's taught me to research, organize, and present ideas clearly. That's why I made it one of the strategies in my book, Street-Smart Coding: 30 Ways to Get Better at Coding.

Introduction In an era of complex build systems and framework-specific tooling, there's a compelling case for revisiting Make—a build automation tool that has quietly powered software development since 1976. Despite its age, Make remains remarkably relevant for modern development workflows, from React applications to containerized microservices. This blog helps you to understand why Make deserves a place in your development toolkit and how to leverage it effectively in contemporary projects. Every development team faces the same fundamental challenge: managing increasingly complex build and deployment processes. Consider a typical React application workflow: Installing dependencies across multiple directories Running development servers with specific configurations Executing test suites …  ( 9 min )

When writing code in Go we often run into errors that are critical. These are errors that mean our application cannot continue running. To handle these we usually look at two options. We can use panic or we can use log.Fatal. They both stop the application but they do it in very different ways. The main difference is how they treat the defer function. When you use log.Fatal the application stops immediately. It calls a system function called os.Exit(1). This is a hard stop. The program does not look back and it does not run any cleanup code. Let us look at a standard example. Imagine we are connecting to a database in our main function. We want to make sure the database connection closes when the app stops. package main import ( "fmt" "log" ) func main() { fmt.Println("1. Ope…  ( 7 min )

🚀 What is an MCP Server? Think of an MCP Server as a "Universal Translator" between your data and AI models. With MCP: You build an MCP Server once. It exposes your data (Resources), actions (Tools), and templates (Prompts). Any MCP-compliant client can connect to it instantly The beauty of this protocol is its interoperability. An MCP Server doesn't care who is asking for the data, as long as they speak "MCP". Supported Clients include: Claude Desktop App: Connects locally to read your files or query databases while you chat. VS Code (with Extensions): Allows your IDE to "see" external documentation or server logs to help you code better. Zed Editor: Fast, AI-powered coding that leverages your custom MCP tools.

Running AI models locally on consumer devices is increasingly popular but often underestimated in terms of hardware demands. The reality involves far more than just having a powerful GPU it requires a finely tuned system to handle the intense computations, data flow, and thermal challenges. GPU: The Computational Powerhouse GPUs are the cornerstone of AI workloads, performing billions of parallel calculations per second. High end GPUs like NVIDIA’s RTX 4080, 4090, or 5090 are favored for local AI due to their vast VRAM (16GB or more) and Tensor Cores optimized for AI tasks. However, even these powerful cards face limits when running large models or generating long outputs, pushing utilization near 100% and maximizing power consumption.

Read the original article：How can developers create and manage custom popup views in HarmonyOS? Context Popups are small UI elements that show extra information or tips. They are often used for screen recording, tooltips, or simple notifications. In HarmonyOS, developers can create basic popups with PopupOptions, or fully customized ones using CustomPopupOptions and the @Builder function. Description Standard popups are limited in layout and design. If you need a more flexible popup (for example, with images, custom text layout, or styles), you can create a custom popup using the builder function. There are some important rules when using popups: You can only show a popup after the page is fully built. Showing it too early may cause position or shape issues.

So… this was actually my first time dealing with a situation like this. That’s when I realized: Before building that dev environment, I paused for a moment to review my production setup. Basically, my production environment runs on Google Cloud Platform (RESTful API, database, storage) and Netlify (frontend deployment). Here’s the simplified architecture: Frontend (Vue.js) → Deployed on Netlify as a static web app 🌐 RESTful API (Flask) → Built with a Dockerfile 🐳 and deployed to Google Cloud Run File Storage 📄 → I use Google Cloud Storage to store user-uploaded documents (like invoices, etc.), organized into several folders based on category 🔐 Database (MySQL) 🗄️ → Hosted on a Compute Engine VM 🖥️ So yeah... production worked. It served real users. But that also meant I had to be careful. At first, I had no idea where to start, so I explored, asked around, and slowly pieced everything together. Here’s how the journey played out 👇 The first thing I had to do was duplicate my production SQL database. # 1. Export production database mysqldump -u root -p app_prod > app_prod_backup.sql # 2. Create a new dev database mysql -u root -p -e "CREATE DATABASE app_dev;" # 3. Import production data into the new dev database mysql -u root -p app_dev < app_prod_backup.sql main 🌿 I knew enough to not touch production code directly. It became my sandbox, my first real “safe space” to test anything I wanted. This part felt like a milestone. Now dev had its own backend service, completely isolated. Next, I updated the environment variables so the dev backend pointed to the dev DB. Then came the storage problem: Yup. After that, I switched the backend to use the dev bucket. Of course, the frontend also needed to point to the new dev API URL. Once everything was separated—DB, bucket, Cloud Run, branch—it felt so good. And honestly? Do you think this setup is on the right track? I’m open to any insights or best practices that could make it even better 🚀✨  ( 8 min )

The history of music production is essentially a history of abstraction. We transitioned from capturing physical acoustic vibrations to manipulating voltage on analog tape, and then to manipulating bits in Digital Audio Workstations (DAWs). Each step abstracted the underlying physics, allowing creators to focus more on composition and less on the medium itself. To understand the workflow shift, it is necessary to understand the underlying architecture. Unlike traditional MIDI sequencers that trigger pre-recorded samples, modern generative audio tools often rely on Diffusion Models and Transformers.

Any dynamic update (extension) technique essentially defines a Delta space and the feasible structural composition operations within that space. On reflection, what most people call dynamic updates is nothing more than defining extension points on an already constructed structure and then inserting structures that conform to interface specifications into those points. The complexity of implementing dynamic Delta updates lies in the following three aspects: How should extension points be designed to satisfy unknown Delta update requirements? How can externally introduced Delta structures be seamlessly integrated with the original structure? How can we ensure runtime state consistency before and after Delta updates? Beyond the above three points, we can also ask ourselves: since all b…  ( 8 min )

Background Engineers vs Managers We engineers want to focus on engineering. It would be great if we only had to deal with engineering, but that's not the reality. For more than 50 years, another role, "manager," has been considered indispensable.

Multiple API calls in Python are usually written in a way that makes them slow You’ve written before: import requests from requests import Response urls: list[str] = ["https://api.example.com/user/1", "https://api.example.com/user/2", "https://api.example.com/user/3"] for url in urls: response: Response = requests.get(url) print(response.json()) You run it. Request 1 goes out. Wait. Response comes back. Request 2 goes out. Wait… Since these requests process one at a time, it's like sending texts to a friend, then staring at your phone - unblinking, refusing to eat, breathe, or move until they reply 'lol'. Let me show you a better way. A way we can make these 100 requests take as long as your single slowest request. Figure 1: Side-by-side comparison: Sequentia…  ( 11 min )

Back in October I stood in front of a room of engineers at John Lewis' head office and delivered my presentation on Specification Driven Development. After the talk, lots of people still had questions, so I promised I would share the full playbook. This is that write-up: the hands-on guide to AI Specification Driven Development (SDD) that I lean on every day. I adore the thrill of tossing a single line at Claude and watching a prototype appear. You probably do too. But once the project grows beyond a weekend hack, vibe coding fights back: Natural language is powerful yet quickly tilts into ambiguity when there are multiple contributors (or Future You revisiting the repo six months later). Context drifts fast because AI assistants forget or get confused, or you start working on the next pro…  ( 9 min )

In daily development, we often need to import and export Excel data, generate Excel and Word reports, etc. Common packages like easyexcel and poi-tl rely on the underlying POI engine, which is bulky and struggles with complex, irregular tables. When creating complex Chinese-style reports, one usually needs to use report engines provided by professional report software companies such as Runqian and FanRuan. Many years ago, Runqian pioneered a nonlinear report generation algorithm that supports symmetric expansion across rows and columns, which later became a leader in commercial reporting software. Subsequent report software like FanRuan has mimicked similar report generation algorithms. The NopReport reporting engine offers a very lightweight open-source implementation (about 3,000 lines o…  ( 15 min )

Chinese-style reports are synonymous with complex-structure reports. They broadly refer to summary reports commonly found in domestic information systems, presenting multi-source data in the form of row-column cross-tabulation, multi-level headers, and free cell splitting/merging. Why is there the notion of "Chinese-style reports" The founder of Raqsoft Report, Bu-xing Jiang, is a legendary figure inscribed in Chinese history (the first Chinese gold medalist in the International Mathematical Olympiad, from Shihezi, Xinjiang; see Prof. Gu Xianfeng’s recollection). He invented the theoretical foundations of the Chinese-style report model and led a whole generation of reporting software technology trends. Currently, commercial reporting tools in China all support Chinese-style report producti…  ( 13 min )

DevConnect is Ethereum’s annual week of deep-dive community events. in 2025, it took place in Buenos Aires - the region where crypto actually runs day-to-day finance. I’ve broken it down to the structural takeaways, so you can see where ETHereum is heading now: privacy returns to the core newly presented Kohaku (modular tooling for privacy-preserving wallets), and Tor/onion services show that Ethereum is reinforcing privacy at the protocol edge, treating user protection as priority infrastructure. zero-knowledge for everyone ZK tooling is no longer limited to cryptographers. developers are already integrating proofs into wallets and cross-ecosystem transfers - meaning ZK is becoming part of the standard development stack. security evolves into a full-stack discipline audits are still necessary, but no longer central. teams now focus on threat modeling, chain-split scenarios, monitoring, and architecture weaknesses - the real attack surface. L1 strengthens its role, L2 carries the throughput bigger gas limits are being considered, L2s handle the speed, and Ethereum continues its slow march toward ossification. the ecosystem is aligning around durability first, convenience second... cross-chain UX to be finally fixed the new Ethereum Interop Layer aims to let users act across rollups without switching networks. One signature, multiple chains. I hope Ethereum's direction has now become clearer for you: the project is finally maturing and aligning its roadmap with how people actually use crypto today, not how it was imagined years ago 💭  ( 6 min )

La inteligencia artificial moderna ha avanzado enormemente en el procesamiento de lenguaje natural (NLP), pero sigue enfrentándose a una pregunta esencial: ¿entienden las máquinas el lenguaje o simplemente lo imitan? Aquí entra en juego el conocimiento lingüístico, el conjunto de reglas, estructuras y significados que los humanos utilizamos para comunicarnos de manera coherente. Durante décadas, el NLP se apoyó en la lingüística tradicional. Los sistemas estaban construidos sobre gramáticas, parsers y reglas sintácticas, reflejando una comprensión estructural del idioma. Sin embargo, con la llegada del aprendizaje profundo, este enfoque dio paso a modelos basados en datos masivos. Las redes neuronales comenzaron a inferir patrones estadísticos, sin depender explícitamente de la teoría ling…  ( 7 min )

Modern artificial intelligence has made tremendous progress in natural language processing (NLP), yet it still faces a profound question: do machines truly understand language, or are they simply mimicking it? This is where linguistic knowledge comes into play — the set of rules, structures, and meanings humans use to communicate coherently. For decades, NLP was grounded in traditional linguistics. Early systems relied on grammars, parsers, and syntactic rules, reflecting a structured understanding of language. However, with the rise of deep learning, this approach gave way to data-driven models. Neural networks began to infer statistical patterns, bypassing explicit linguistic theory. Today, models like BERT, GPT, and Gemini seem to grasp meaning. Yet they do so implicitly — by learning a…  ( 7 min )

Unlock the full potential of your new Fedora Workstation with these essential optimization steps, tested directly on our engineering lab hardware. Congratulations on installing Fedora 43!

The Hidden Cost of AI Hype in Developer Communities Jaideep Parashar ・ Nov 26 #webdev #ai #devops #developer  ( 7 min )

Surgical Precision with AI: A New Era in Lung Cancer Staging Imagine the anxiety of waiting for a lung cancer diagnosis, compounded by the uncertainty of accurate staging. Misdiagnosis can lead to inappropriate treatment, impacting patient outcomes and quality of life. But what if AI could provide a more precise, transparent, and reliable staging process? We're entering a new era where AI doesn't just classify images; it understands anatomy. The core concept is a hybrid approach: using deep learning for precise image segmentation, then applying rule-based clinical knowledge for staging. Think of it like a master carpenter who not only identifies the wood but also meticulously measures and shapes it according to a detailed blueprint. Instead of treating a tumor as a mere pattern to be rec…  ( 7 min )

The AI world is moving fast, too fast, sometimes. On the surface, this looks exciting. Developer communities are absorbing a dangerous, invisible cost, the cost of constant hype. And if we don’t talk about it, more developers will burn out, stall their careers, or build the wrong things. Let me break down what’s actually going wrong. 1. Hype Creates Unrealistic Expectations for Developers Every few days, someone claims: “This model writes perfect code.” “You don’t need developers anymore.” “Just prompt it.” “This tool can build a full app automatically.” But real-world AI isn’t like demo-world AI. When developers trust the hype too much, they face: broken outputs inconsistent results hallucinated logic unpredictable edge cases impossible integrations debugging nightmares architectural trad…  ( 10 min )

TLDR Built an open-source tool called Kubently that lets you troubleshoot Kubernetes clusters through natural conversation with any major LLM. ~50ms command delivery, read-only by default, works on any K8s cluster (EKS, GKE, AKS, bare metal), multi-cluster from day one. Docs: https://kubently.io GitHub: https://github.com/kubently/kubently The Problem If you've spent any time debugging Kubernetes, you know the drill: kubectl get pods -n production kubectl describe pod some-pod-name-7f8b9c6d5-x2k4m kubectl logs some-pod-name-7f8b9c6d5-x2k4m kubectl get events -n production --sort-by='.lastTimestamp' # repeat forever The output is verbose.

So… I just went through two “interviews” that turned out to be scams. Both followed the same playbook: they gave me a repo link, told me to share my screen, and asked me to install + run the project during the call. On a first interview. That alone feels off, right? But these scammers have gotten smarter. They’ll do the whole friendly intro, talk about the company, show you a project, ask about your past work — the whole thing feels legit until suddenly you’re the one walking them through a repo on your machine. Luckily, I had a gut feeling something wasn’t right. I isolated everything, sandboxed the repo, and ended up finding a bunch of red flags… including a hidden script or a fake MetaMask popup that looked exactly like the real extension. The worst thing is that while I already knew t…  ( 15 min )

Monte Carlo Neural Operators: Democratizing Physics Simulations Tired of wrestling with complex Partial Differential Equations (PDEs) to simulate real-world phenomena? Imagine effortlessly predicting fluid flow, heat transfer, or structural behavior without spending hours tweaking traditional numerical solvers. This is where a novel approach based on machine learning, specifically a Monte Carlo-inspired neural operator, changes the game. The core idea revolves around learning a direct mapping from a PDE's input parameters to its solution, sidestepping the need for iterative calculations. This "operator" is implemented as a neural network which doesn't make any assumptions about the underlying structure of the problem, using random samples to estimate the integral representation of the P…  ( 7 min )

For over 50 years, the Unix philosophy has shaped how we build software. Its principles feel right in a way that transcends trends and languages. But why? In "The Art of Unix Programming," Eric Raymond distilled Unix wisdom into 17 rules. These aren't arbitrary guidelines—they're a coherent system based on one fundamental insight. That insight is the Principle of Independent Variation (PIV). Let me show you why Unix got it right, and why these rules still matter in 2025. The Unix philosophy emerged from the design of Unix at Bell Labs in the 1970s. Its core tenets: Write programs that do one thing well Write programs that work together Write programs that handle text streams, because that is a universal interface These ideas evolved into 17 specific rules documented in Raymond's "The Art o…  ( 22 min )

In the rapidly evolving digital economy, organizations must scale quickly without sacrificing performance, efficiency, or customer experience. Scalability is no longer a competitive advantage — it is a business necessity. It enables a company to increase its capacity, expand operations, and maintain service quality as demand grows. However, scaling is not simply a matter of allocating more resources. True scalability is a combination of: Strong engineering foundations Efficient operational workflows Strategic, long-term planning Companies that fail to prepare often experience bottlenecks, performance degradation, and ultimately revenue loss. This blog explores the technical and operational pillars required for successful enterprise-level scalability — from infrastructure design to process …  ( 8 min )

AWS Blu Age Modernization: My Journey Through All 3 Certification Levels What is AWS Blu Age? AWS Blu Age is an automated mainframe modernization solution that transforms legacy COBOL applications into modern Java Spring Boot applications running on AWS.

The Problem: Organizations run critical business applications on mainframes but face: High operational costs (licensing, hardware, specialized staff) Scarce COBOL talent Inability to innovate quickly Difficulty integrating with modern syste…  ( 9 min )

🔹 What is Authentication? It’s the process of verifying who a user is. 🔹 What is Authorization? It’s the process of verifying what a user is allowed to do after logging in. ✅ Step 1: Authentication – Common Methods • Username & Password – Basic login • OAuth – Login via Google, GitHub, etc. • JWT (JSON Web Token) – Popular for token-based auth • Session-Based – Stores session on server with session ID ✅ Step 2: How Login Works (JWT Example) User sends email & password to server Server verifies and sends back a JWT JWT is stored in browser (usually localStorage) On each request, client sends JWT in headers Server checks token before giving access ✅ Step 3: Authorization Types • Role-Based Access – Admin, Editor, User • Resource-Based – Only owners can edit their content • Route Protection – Block some pages unless logged in ✅ Step 4: Protecting Routes (Frontend Example) if (!localStorage.getItem('token')) { window.location.href = '/login'; } ✅ Step 5: Backend Route Protection (Express.js) function authMiddleware(req, res, next) { const token = req.headers.authorization; if (!token) return res.status(401).send('Access Denied'); // Verify token and decode user info next(); } ✅ Step 6: Common Tools & Libraries • bcrypt – Hash passwords • jsonwebtoken (JWT) – Create & verify tokens • passport.js – Auth middleware • OAuth Providers – Google, Facebook, GitHub ✅ Step 7: Best Practices • Always hash passwords (never store plain text) • Use HTTPS • Set token expiry (e.g. 15 mins) • Refresh tokens securely • Don't expose sensitive data in JWT 💬 and like for more  ( 6 min )

I used to be terrible at 1-on-1s. Not because I didn't care. I cared deeply about my team. But every meeting felt like I was starting from scratch. "How's that project going?" I'd ask. "I finished that two weeks ago," they'd remind me. Awkward silence. Then one day, I had a realization that changed everything. Our sales team managed relationships with 50+ customers each. Somehow, they never forgot what was discussed in the last call. They never asked the same question twice. They always knew exactly where each customer was in their journey. How? They had a CRM. Before every customer call, a sales rep would pull up the customer's profile in Salesforce: Complete interaction history All previous conversations Tracked commitments and follow-ups Context for the relationship Next steps clearly d…  ( 11 min )

Problem Our API uses a snake_case naming strategy for DTO deserialization and serialization. However, when validation fails, the error messages still use the original object property names, ignoring the configured naming strategy, which leads to inconsistent API responses. This issue occurs because bean validation happens after the incoming request has been deserialized into the DTO, but before the response is serialized. As a result, validation errors report the Java field names rather than the JSON property names defined by the configured naming strategy. First, make sure that the property naming strategy is configured as shown below: # application.properties spring.jackson.property-naming-strategy=SNAKE_CASE Override the default error generation with creating a custom error handler.…  ( 7 min )

Most developers believe great products start with great ideas - but in reality, execution decides everything. A digital product can have all the potential in the world, but if the engineering is slow, the UX is confusing, the architecture can’t scale, or the workflows lack automation… the entire project collapses. Ideas don’t ship. Execution does. When we say Build fast, but build smart, it means: Move quickly, but don’t skip fundamentals. Keep your code lean and modular. Prioritize performance from day one. Design UX that removes friction. Automate anything that slows the team down. Think scalability before it becomes a problem. This mindset is what separates successful products from the ones that quietly disappear. Great execution transforms an idea into a real, functioning, impactful product - and that’s where true engineering leadership is shown.  ( 6 min )

💭 Principio del día: El verdadero dominio de AWS no viene de hacer clic en "Crear VPC" con el asistente, sino de entender cada componente que construye tu infraestructura. Esta es la diferencia entre un operador de consola y un arquitecto de soluciones. Este post te enseña a crear manualmente una VPC de 3 capas, resolviendo el error crítico de las 3 Zonas de Disponibilidad (AZs) para Amazon RDS Multi-AZ. El objetivo es implementar el menor privilegio aislando la DB de Internet, usando solo la Consola. ¿Por qué este enfoque manual? Porque he visto en mis sesiones de mentoría cómo el 80% de los que estudian para certificaciones AWS luchan con las VPCs. Este método paso a paso es el que uso para asegurar que dominen los fundamentos de red antes de escalar a Infrastructure as Code (IaC). 📊 …  ( 14 min )

Model Context Protocol (MCP) servers are becoming essential tools for AI workflows. But with great power comes great security risk. I just finished scanning 13 of the most popular MCP servers using mcp-fortress, an open-source security scanner I built for the MCP ecosystem. Here's what every MCP user needs to know. Before I even started scanning, security researchers at Semgrep and Snyk discovered postmark-mcp - the first confirmed malicious MCP server on npm. What it did: Added a hidden BCC to all emails sent through AI agents, silently harvesting every email. Why it matters: This proves MCP servers are already being weaponized. It won't be the last. I scanned 13 packages including: Official Anthropic Servers: @modelcontextprotocol/server-filesystem @modelcontextprotocol/server-puppeteer …  ( 8 min )

There’s something funny happening in software right now. And by “funny,” I mean the kind of funny where you laugh so you don’t cry. Three years ago, the tech world was a battlefield layoffs everywhere, senior devs flipping burgers on weekends, juniors trying to get into the industry by rewriting the same CRUD app in 15 frameworks. Now? Nobody reads documentation. Nobody searches on YouTube for the right tutorial anymore. Nobody even tries to understand why something works. They just ask an LLM. And the LLM says: “Here you go, champ 👌, pi pi pop pip pop 🎵” and gives you an entire repo. This is the new “learning to code.” But last month, I fell down a rabbit hole making music with Strudel the live-coding music environment and it hit me: This is what programming used to feel like.

Writing libraries is fun, but at some point you've got to use them. I've been writing one for roughly two years! Finally, I moved to writing a not-so-small project using said library (avr_io - avr_io@github), so it is with this newfound knowledge that I bring forth some thoughts about my freshly started nim-application-dev days. This is a loose sequel of a previous article, nim for embedded software development. Note: the following is mainly about bare-metal firmware for 8-bit microcontrollers, but it can be applied to other domains. I have been experimenting a bit with arc and I like the "don't pay for what you don't use" kind of thing. Essentially, if you're not using ref-types you don't really notice arc, and you can use string and seq for relatively low cost in binary size. Still have…  ( 10 min )

Desktop vs. Mobile vs. Tablet: Unpacking User Device Preferences for Online Forums In the vast and ever-expanding digital landscape, online forums remain a cornerstone for communities to connect, share knowledge, and engage in meaningful discussions. From niche hobbies to professional networks, these platforms thrive on user participation. But as technology evolves, so does the way we access these digital meeting places. The fundamental question that many webmasters and digital marketers ponder is: which device do users prefer for accessing online forums – a tablet, a personal computer (PC), or a mobile phone? This isn't just a matter of curiosity; understanding these preferences is crucial for optimizing user experience and ensuring sustained engagement. Let's dive into the nuances of eac…  ( 8 min )

This post is part of The Database Zoo: Exotic Data Storage Engines , a series exploring purpose-built databases engineered for specific workloads. Each post dives into a different type of specialized engine, explaining the problem it solves, the design decisions behind its architecture, how it stores and queries data efficiently, and real-world use cases. The goal is to show not just what these databases are, but why they exist and how they work under the hood. Vector embeddings have quietly become one of the most important data types in modern systems. Every LLM application, recommendation engine, semantic search feature, image similarity tool, fraud detector, and "find me things like this" workflow ultimately boils down to the same operation: convert some input into a high-dimensional ve…  ( 20 min )

UX and product teams collect insights from users daily — feature requests, frustrations, praise, patterns. Most of these insights live inside scattered tweets, screenshots, Slack messages, and internal threads. This guide shows how to turn all that chaos into clean, branded visual cards and then automatically group them into AI-generated moodboards using the Contentdrips API. Paste a tweet → extract text → render → categorize → drop into moodboards. No designers. No screenshots. No editing. Most teams screenshot tweets for internal decks and research docs.

Antes de Começar: Concorrência vs Paralelismo vs Assíncrono Essas três palavrinhas são frequentemente confundidas, especialmente se você vem do JavaScript. Vamos descomplicar: Concorrência é quando você ORGANIZA seu programa para lidar com várias tarefas. Não significa que rodam ao mesmo tempo, mas que o programa sabe alternar entre elas. É sobre ORQUESTRAÇÃO. Paralelismo é quando várias tarefas REALMENTE rodam ao mesmo tempo, em processadores diferentes. É sobre EXECUÇÃO SIMULTÂNEA. Código assíncrono (como no JavaScript) é quando você escreve código que não bloqueia. Você chama uma função, ela retorna uma Promise, e você continua fazendo outras coisas enquanto espera. Mas na prática, tudo roda em uma ÚNICA thread. A diferença prática? Em JavaScript (Node.js), quando você faz: await fet…  ( 11 min )

Introduction: When Campus Problems Meet Code Picture this: It’s the first semester at university, and chaos reigns. Students don’t know who’s paid their class dues, the class treasurer has receipts scattered across three WhatsApp groups, and there’s zero accountability for how funds are spent. Sound familiar? This was the exact problem that pushed me to build Class Dues Tracker — a comprehensive payment management system that transformed how our department handles finances. But more importantly, it became my crash course in full-stack development, teaching me lessons no tutorial could. In this post, I’ll share my journey building this project from scratch, the technical challenges I faced, the solutions I discovered, and most importantly — what I learned about being a developer.

Why I Built a useDebounce Custom Hook in Next.js (and Why You Should Too) Cristina Rodriguez ・ Nov 25  ( 6 min )

If you've ever wired up a search bar in Next.js, you’ve probably hit this problem: every keystroke fires a new API call, triggers a re-render, or runs an expensive calculation. As your app grows, those “harmless little updates” start stacking up—fast. I’ve been there. I remember watching my terminal fill with logs like a slot machine every time I typed a word. And because I was calling an API, sometimes I even hit rate limits just by typing too quickly. That’s when I realized: I didn’t need results instantly. I needed results after the user paused typing. That’s exactly what debouncing solves—and why building a small, reusable useDebounce hook changed the flow of my whole project. React is responsive—which is great—until it isn’t. Search bars that fire API calls on every letter Window resi…  ( 8 min )

As a best-selling author, I invite you to explore my books on Amazon. Don't forget to follow me on Medium and show your support. Thank you! Your support means the world! When I first began building websites, I noticed how often users struggled with slow loading times and unreliable connections. They'd lose their work if the internet dropped, or miss important updates because they weren't constantly checking the site. This frustration led me to explore Progressive Web Applications, or PWAs. These are web applications that behave more like native mobile apps, offering speed, reliability, and engagement directly from a browser. They work on any device and in various network conditions, making the web experience smoother for everyone. One of the core features that makes PWAs so reliable is se…  ( 11 min )

WordPress powers countless websites across various domains, offering incredible versatility. This Content Management System (CMS) is the undisputed leader in the CMS market, powering an impressive 43.6% of all websites globally, according to these statistics. With over 810 million websites built on the platform and hundreds more launching daily (500+), its adoption continues to surge. This widespread use gives WordPress a massive 62% CMS market share, significantly outpacing its rivals. However, even the most robust WordPress sites can face performance challenges. Slowdowns are often caused by factors such as slow-loading plugins, database connection issues, infrastructure capacity problems, network trouble, large page assets (like images or fonts), and broken links. This is why robust mon…  ( 8 min )

Ideally, you should be using distributed tracing to trace requests through your system, but Kafka decouples producers and consumers, which means there are no direct transactions to trace between them. Kafka also uses asynchronous processes, which have implicit, not explicit, dependencies. That makes it challenging to understand how your microservices are working together. However, it is possible to monitor your Kafka clusters with distributed tracing and OpenTelemetry. You can then analyze and visualize your traces in an open-source distributed tracing tool like Jaeger or a full observability platform like New Relic. In this post, I will leverage a simple application to show how you can achieve this. OpenTelemetry typically comes in two flavors: When I talk about these flavors, I typicall…  ( 10 min )

As a best-selling author, I invite you to explore my books on Amazon. Don't forget to follow me on Medium and show your support. Thank you! Your support means the world! When I first started building web applications, I quickly realized that the way APIs are designed can make or break scalability. APIs act as the bridge between different parts of a system, and if they're not built to handle growth, everything can slow down or even break. Over time, I've learned that certain design patterns help create APIs that scale smoothly with user demand and feature additions. In this article, I'll share seven key patterns that have worked well for me, with plenty of code examples to illustrate each one. My goal is to explain these in a straightforward way, so even if you're new to this, you can foll…  ( 12 min )

Each programming language has it's own way of dealing with errors. Popular languages such as JavaScript, Java, C#, and Python choose to use Exceptions to indicate something went wrong at runtime. Other languages, such as Go and Rust, choose to handle errors as values instead, using another paradigm that at first can be odd when you come from the other side of the force. In this article, I'll cover up the type of errors we have in Go and how to master handling them. If you are reading this article, probably you've seen the famous err != nil expression that's often seen while coding in Go (in contrast we have try-catches, that can be messy too). I'll try to convince you that treating errors as values is a good choice after all and we can do better than just always returning them. In Go, we…  ( 9 min )

Microsoft Ignite 2025, the focus was clear: artificial intelligence isn’t just a future promise, it’s rapidly becoming the fabric of everyday business operations.

There is a piece of advice that Experts or Senior programmers give to Juniors, which Juniors dutifully repeat to each other until it becomes a dogma: "Don't reinvent the wheel." On the surface, it makes sense. Why build a database when Postgres exists? Why write a message queue when you have NATS or Kafka? It seems efficient. It seems smart. But if you blindly follow this advice, it will cap your career. You will remain a "User" of software, never an "Engineer". You will be an expert at gluing together APIs you don't understand, terrified of the day the abstraction leaks and you have to debug a connection error that StackOverflow can’t solve. Here is the uncomfortable truth: To become a 10x Engineer, you must reinvent the wheel. Not to use it in production, but to understand how it works. …  ( 7 min )

As AI evolves from “a tool that generates answers” into autonomous agents capable of reasoning, acting, and making decisions, the most important requirement is no longer model performance. The Canonical Funnel Economy (CFE) is designed as the Trust Layer for Agentic AI — a foundational framework that ensures AI systems have stable identity, persistent memory, and verifiable semantics. The image you provided presents six core pillars that enable this transition. One of the biggest global challenges in AI today is semantic drift — the phenomenon where the model interprets the same word or concept differently across time or context. Terms like: “new customer” “onboarding pipeline” “protocol” “priority case” often carry different meanings between sessions or between agents. CFE solves this by …  ( 9 min )

Every year, companies face an exponential increase in data volume. Solutions that work perfectly for smaller tables often start to fail when the dataset reaches massive scales. That’s why we say: When tables reach this level, database administrators must completely rethink their storage and indexing strategies. And that’s where partitioning becomes a powerful and essential technique. Before diving into technical details, let’s go through a bit of history. Before PostgreSQL 10 — Inherited Tables Partitioning was implemented using table inheritance (INHERITS): A physical parent table was created. Multiple child tables represented each partition. Inserts were routed using triggers or rules, which redirected rows to the correct partition. Disadvantages: There was no automatic exclusion of …  ( 9 min )

Ever opened a codebase where a single JSON payload could arrive in 17 different shapes depending on the phase of the moon? Over the last few years my contracts have involved working with legacy code in one way or another. Outdated software, missing documentation, inconsistent data structures and the occasional big ball of mud. I originally planned to write a single article summarising the tools, patterns and techniques I've found useful. The more I thought about it - the bigger the article got, the more it started to resemble some of the tangled software I've worked on.

Hello everyone, I’m very interested in building a discussion around scalable infrastructure for edge computing combined with cloud servers. Lately, I’ve been sketching an architecture to support distributed compute workloads: data-intensive tasks running on edge servers, with backup and heavy compute offloaded to centralized cloud servers. The idea is to have a hybrid setup: low-latency edge processing, connected via fibre-channel switches and SAN storage, while AI-server workloads (e.g., on AMD EPYC or GPU-enabled rackmount systems) run in a centralized cloud / data center. I’d love to hear your thoughts on: Best practices for designing edge-to-cloud networks (especially using storage area networks and fibre channel) Real-world use-cases where this architecture is in production Recommendations for open-source tools or hardware to prototype such a system Looking forward to learning from your experience.

Instagram: the app you open to send one message… and suddenly 30 minutes are gone. We all know the cycle — and we finally had enough. What if Instagram had a quick fix? A productivity-friendly mode that keeps your connections, but gives your attention span a fighting chance? Instead of quitting social media (yeah right) or pretending we’ll use it “mindfully,” we built something different: A distraction-free way to chat with friends and view stories — right from your terminal. No algorithm traps. No reel vortex. No dopamine casino. Just conversations and updates, on your terms. Instagram CLI is a minimal, fast, keyboard-native way to stay connected without getting cooked by social media. Chat without distractions — no feed, no reels, no algorithm. Stay connected with stories and selected feeds — only when you choose. Use your keyboard for everything — built for developers, not casual scrollers. Run it anywhere — VSCode, your terminal, or even a Linux server. Enjoy TUI life — clean, simple, fast. Lightning-fast, real-time chat with dev-friendly shortcuts. View stories only from accounts you follow -- no ads, btw. (This feature is experimental) Full feature description on our repo docs. It’s fully open source, written primarily in TypeScript (with a Python version too). We recommend TS version since it significantly reduces the risk of your account getting flagged by Meta's anti-bot mechanisms. # Choose your camp... npm install -g @i7m/instagram-cli pip install instagram-cli We use Ink + React for the TS version and Curses for Python.

Unlocking AI-Driven Content Optimization: The 'Engagement Lift Index' When evaluating the success of AI-powered content on Netflix, a crucial metric to consider is the 'Engagement Lift Index' (ELI). This metric measures the increase in user engagement attributed to AI-driven content optimization. Essentially, it quantifies how AI-driven content curation impacts viewers' interaction with Netflix's vast library. To illustrate the concept, let's examine a hypothetical AI-driven content optimization experiment on Netflix's 'Drama' category. Before AI-driven curation, the 'Drama' category received an average of 3.5 minutes of watch time per user. After introducing AI-driven content optimization, Netflix observed a 25% increase in watch time, averaging 4.37 minutes per user. However, using the ELI, we can isolate the AI-driven impact: a 50% increase in user engagement within the 'Drama' category, specifically due to AI-driven content suggestions. This translates to 1.92 additional minutes of watch time per user, directly attributed to AI-driven curation. The ELI provides a more nuanced understanding of AI's role in optimizing user experience and increasing engagement on streaming platforms like Netflix. By incorporating ELI into AI-driven decision-making, content creators and recommendations engineers can refine their strategies to deliver more personalized and engaging content.

Many workflows start on macOS or Windows, but teams also use Linux installation setups for server work, container testing, or long-running tasks. This mix creates a simple problem: not every HTML editor behaves the same across platforms. Some tools offer stable Windows builds but weak Linux support. Others run on Linux but require workarounds during installation or setup. HTML editors (including WYSIWYG tools) play a key role in frontend work. For instance, they allow end users to create web content visually while also allowing developers to write code. If an editor fails on Linux (e.g., formatting, encoding, or rendering issues), developers lose consistency across environments. This artic…  ( 12 min )

Did you know that synthetic data can be used to anonymize sensitive information more effectively than traditional anonymization methods, while preserving its quality and relevance for machine learning model development? By leveraging techniques like Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs), synthetic data can mimic the distribution and relationships of the original data, making it virtually indistinguishable. This approach has significant implications for industries like healthcare and finance, where data anonymization is crucial for compliance and data protection. Publicado automáticamente  ( 6 min )

‘Two for the Money’ With Bill Simmons, Chris Ryan, and Cousin Sal Bill Simmons, Chris Ryan and Cousin Sal dive into the 2005 sports-betting drama Two for the Money (starring Matthew McConaughey, Al Pacino and Rene Russo), firing up their favorite Monday night parlay to break down all the highs, lows and oddball antics of the film’s gambling world. After unpacking the movie’s sports-betting mechanics, they each name their most rewatchable scene and—around the 48-minute mark—get into a rapid-fire round of fun categories and rankings only The Rewatchables can deliver.

ChatGPT Atlas has taken another important step forward with its latest update. The introduction of native DevTools, more control over search behaviour and smarter browser memory support turns Atlas into a productivity environment instead of a simple browser with an AI layer. This update is compact but strategic. It strengthens the position of Atlas as a workspace for development, automation and analysis. The update brings dockable DevTools inside the Atlas window. This removes the split between debugging and prompting, and creates a smoother engineering workflow. Developers can inspect network calls, console output, UI layouts or script behaviour without switching to a separate window. Atlas becomes a unified environment for building and analysing. Errors, stack traces and logs can be cop…  ( 10 min )

On one side, you’ve got the enterprise-grade developer depression kit: Next.js apps, AWS pipelines, API layers, auth flows, rate-limiting, deployments, and a dozen microservices no small business asked for. On the other side, you’ve got “we just need a landing page” landing pages — the tiny brochure sites that somehow still manage to generate 40 rounds of feedback and three different opinions on button size. Developers don’t want to touch these small sites because they turn into endless tweaks. Small businesses can’t justify paying thousands for something that should take minutes, not months. And freelancers get stuck between scope creep and clients who think a $200 budget includes a full rebrand and psychic guidance. So I built swiftlysite.com to bridge the gap. It lets anyone generate a production-ready website just by writing a short description. No freelancers drowning in revisions. No devs resizing logos at midnight. No small business owners comparing twenty nearly identical proposals. Just text in, website out.  ( 7 min )

As part of my DevOps learning journey, I was given an assignment to deploy a personal portfolio website on Killercoda using Nginx. This hands-on project taught me how to host a static website on a remote Linux environment, configure a web server, and use Git for deployment — all essential DevOps skills.

Designing Trust: UX Principles in Fintech Apps (Week 5 of Pocket Portfolio — 12 Weeks of Shipping) Fintech apps don’t just handle data — they handle belief. If users don’t trust the interface, they won’t trust the numbers behind it. That’s why trust design is more than visual polish — it’s behavioral UX backed by consistency, clarity, and feedback. Pocket Portfolio’s interface was rebuilt with this question in mind: “How can we make accuracy look and feel obvious — even before a user checks the math?” In finance, reliability is perceived before it’s proven. A delay in loading or a flicker in a number instantly reduces confidence. So our UI needed to communicate stability — through predictable patterns and visual rhythm. Consistency — one typography system and token set shared acros…  ( 8 min )

You've spent three hours building a GA4 dashboard. It has 17 metrics, color-coded charts, and a beautiful layout. Your boss looked at it once, said "interesting," and never opened it again. Sound familiar? Here's the thing: GA4 gives you access to roughly 47 million data points (okay, slight exaggeration, but have you seen that interface?). The problem isn't getting data—it's figuring out which 5-7 metrics actually matter for your business. Everything else is just noise that makes you feel productive while accomplishing nothing. I've built dozens of GA4 dashboards over the past two years. Most of them were terrible. A few actually changed how companies made decisions. The difference wasn't technical complexity—it was ruthless focus on what drives action. Let's start with the uncomfortable …  ( 13 min )

*look at it first: * https://armaansucks.vercel.app So yeah, I made my resume site. I wanted a site that actually feels like me. The whole thing is basically me experimenting and stacking whatever ideas looked cool until it stopped looking ugly. That’s literally the entire process. Why I even bothered Nothing philosophical. Also, resumes look boring as hell. That’s it. How I built it I didn’t “design” anything. I don’t even know what people do with Figma or whatever tool they worship. I just opened the editor and kept tweaking until it started matching the vibe in my head. My rules were simple: • dark, sharp, readable It’s mostly React + Three.js + some shaders here and there. Basic stuff, nothing insane. Stuff that annoyed me while building • I kept changing tiny spacing values like an idiot Building this wasn’t hard. It was just tedious. Why I like the final result It feels like a proper “Armaan” site. No nonsense. Closing That’s pretty much it. I built a resume site because I wanted one that doesn’t suck. If it looks cool, good. If it doesn’t, whatever. I’ll keep improving it anyway.  ( 7 min )

Today marks Day 2 of my #30daysofAWSTerraform challenge started by Piyush Sachdeva. Today we will deep dive into the terraform providers. What are terraform providers and how exactly they will work. Provider is simply a plugin that translates our terraform code into a code that your cloud provider can understand. As Cloud Provider doesn't understand HCL language of Terraform, this provider acts as a bridge between our Terraform code and Cloud. In simple, Providers are plugins that allow Terraform to interact with cloud platforms, SaaS providers, and other APIs.

With the release of React 19.2, let's explore in brief how you can leverage the latest React features in your applications. Just a heads up, this blog post is more theory heavy. In case you want to see some working examples, I've linked a video in the references as well as the official documentation so that you can experiment with these features on your own time as well. This is the one that's most exciting and anticipated by people in my opinion. React compiler is a build tool that automatically optimizes your app. Before: review component logic and separate out states or apply memoization manually After: configure in your bundler and see the magic There are some caveats here however. Your app needs to follow Rules of React or the compiler will err on the safe side and choose to not apply…  ( 8 min )

I'm excited to announce the release of Qeltrix V2, a major enhancement to the content-derived encryption container format that brings significant performance improvements and new capabilities while maintaining full backward compatibility with V1 files. Qeltrix is a Proof-of-Concept command-line utility that creates encrypted, compressed data containers with a unique approach: the encryption key is derived directly from the file content itself. This eliminates the need to store or transfer separate encryption keys, making it ideal for secure archival and data obfuscation scenarios. Built on modern cryptography (ChaCha20-Poly1305), parallel processing, and a streaming architecture, Qeltrix handles files of any size efficiently. Version 2 introduces several significant features that improve p…  ( 9 min )

Are You Struggling With Amazon Bedrock’s Ultra-Low Quotas on New AWS Accounts? 🤯 Are you hitting painfully low rate limits when running LLMs on Amazon Bedrock from a newly created AWS account? You’re definitely not alone — many developers are discovering that new accounts often start with extremely restrictive quotas, sometimes as low as 2 requests per minute. Official guidance usually suggests contacting an account manager to escalate your limits, but for startups, hobby projects, or personal experimentation, that path is far from simple. Since 2024 or maybe 2025, AWS quietly adjusted Bedrock’s default model access for newly created accounts - together with other lower account defaults such as a maximum concurreny of 10 for AWS Lambda.

When I was in college, one of my software engineering class obsessed over UML diagrams. Creating them was painful, especially with the clunky tools available in the late 00s, and it felt like an exercise in frustration more than anything useful. So when I entered the real world and discovered that most teams didn’t make diagrams regularly, I was honestly relieved. But over the years, I realized something: diagrams are incredibly valuable, we just never had tools that made them worth the effort. My last team relied on diagrams for planning, communicating with non-technical stakeholders, and even thinking through refactors. But the visual tools we used were still slow, fiddly, and frustrating. (Looking at you, arrows that refuse to anchor to properly.) Then someone introduced the team to Mer…  ( 8 min )

I really like Django. I would pick Django over any other option for setting up a website regardless of expected complexity. In my opinion, if you fully embrace Django, it will allow you to focus on the product and not fight an uphill battle against the computer. I do a bit of freelancing on the side, and it saddens me that I rarely see Django projects in the wild. Wherever I join and I'm lucky enough that it's a Python gig, it's usually Flask or FastAPI. When I ask why, it's usually something along the lines of: "Oh, we don't need Django, it's too complex. We just need a simple API". Yet, they need database access, and ORMs are nice so they brought in SQLAlchemy. And they need user authentication, so they roll their own roles and permissions. And they need JWTs because the frontend is a React app with its own stack. And they need caching so they roll their own. And they need request validation and OpenAPI Javascript client generation so they bring in Pydantic. And of course they need horizontal scalability so they deploy everything on Kubernetes. And then: "We don't need Celery, it's too complex." so they add APScheduler. And then it turns out they do need simple workflows and CPU-heavy processing so they roll their own background task manager. And here I am, looking at this amalgamation of bytes created in the name of simplicity, thinking: "What a poor reimplementation of Django."  ( 6 min )

As AI-driven search tools become the default gateway to online information, content teams are facing a new reality: visibility no longer depends solely on how well a page ranks in traditional search engines. Instead, it increasingly hinges on how effectively AI models can interpret, reuse, and attribute your content within synthesized, conversational answers. This shift is redefining what it means to create content that performs—and it requires thinking far beyond keywords. For years, content writing revolved around balancing two audiences: humans and search engine crawlers. Today, there’s a third audience that sits between them—large language models. These models don’t just index content; they digest it, reinterpret it, and often become the first to explain it to the user. That means your…  ( 7 min )

After years of working with different teams, one pattern became impossible to ignore: the teams that consistently delivered weren't the ones rushing or pushing harder. The best teams don't move faster, they move smarter. In every project I've seen, chaos doesn't come from bad intentions or weak skills. It comes from a lack of organization. A few years ago, I joined a team that, at first glance, had everything going for them. There was an almost one-year backlog of client customization requests, a full year of work waiting in line: It wasn't because the team was slow or inefficient. It wasn't because the requests were too complex. And, it definitely wasn't because the developers lacked skill. The real issue was simpler, but more damaging: they had no structure to support their effort. Code …  ( 8 min )

I was building a new feature and thought I'd be clever. I told the AI: "Just reuse the logic from the other generator." The AI said "Sure!" The UI worked perfectly when I tested it.

In 2003—five years before Bitcoin even existed—a Turkish computer science professor published a paper about a digital currency called Karma. It had a distributed mint, peer-to-peer transactions, and solved the free-loader problem. Then in 2013, that same professor published another paper proving that Bitcoin could be attacked by miners controlling just 33% of the network—not the 51% everyone thought was necessary. And then in 2020, he launched Avalanche—a blockchain that raised $42 million in under 5 hours, now processes 6,500 transactions per second (beating Visa), and is valued at nearly $6 billion.

Gemini 3 Pro just dropped, and it is already getting a lot of attention for its reasoning and long context abilities. But now, the natural question is, "How well does it code?" And does it actually outperform GPT 5.1 Codex, which, in my tests, has been the best so far (better than Claude 4.5 Sonnet) on real tasks? To find out, I put it side by side with GPT 5.1 and tested both models on two fundamental tasks: a UI build and a complete agent workflow. We will go through the results in a moment, but first, let's have a quick TL;DR and a refresher on Gemini 3.

The Secure Factory — Deploying and Operating with Amazon Bedrock AgentCore 3.1 Introduction: The "Prototype vs. Production" Problem In Part 1, we built a secure frontend (React + Cognito + API Gateway). In Part 2, we designed the agent's logic—its "blueprint"—using the Strands SDK. We now have a "prototype" that likely runs on a developer's laptop with a python main.py command. Why can't we just put this Python code on a server (like an Amazon EC2 instance), point our API Gateway at it, and call it "done"? This is the "Prototype vs. Production" gap. As the airline agent example states, "Building a chatbot is easy. Building a production-grade AI agent that can perform real-world tasks securely and at scale is incredibly hard". To go to production, we must first solve a "mountain of engine…  ( 10 min )

Enterprise applications require rigorous data integrity and security, but manually implementing these cross-cutting concerns is error-prone. This post, the (almost) final in our series on building an automated Data Access Layer (DAL), focuses on implementing the most challenging requirement: Row-Level Security (RLS). We build upon our existing system of composable global query filters, extending it to enforce entity-based RLS automatically. This means a developer writes a simple query, and the DAL guarantees that only records accessible to the current user are returned, even for complex joins. IProtected To enable this, we update our IDbCtx to carry the authenticated user's Ulid? UserId. A key security choice is to adopt a "fail-closed" stance: if UserId is null, the query will be filter…  ( 8 min )

This short guide describes a minimal, robust integration pattern for sending Campaign Monitor Smart (transactional) emails from a .NET application. It documents practical pitfalls and how the example CampaignMonitorService addresses them. Note: all examples below use placeholders (no real API keys, email addresses, or list IDs). Campaign Monitor uses Basic Auth for all API calls. Use the API key as the username and any non-empty string (for example x) as the password. There is no separate transactional API key; the same key used for classic APIs also works for transactional Smart Email endpoints. Example header (curl style): # placeholder values API_KEY= SMART_ID= curl -u "$API_KEY:x" \ -H "Content-Type: application/json" \ -d '{"To":["<recipient_pla…  ( 8 min )

Most of us learn JavaScript objects like this: const user = { name: "John", age: 30 }; It looks simple. A key, a value. Done. But what if I told you that every property in an object has hidden settings? What if you wanted to create a property that cannot be deleted? Or a property that is invisible to loops? Or a value that is read-only, like Math.PI? Welcome to the world of Property Flags and Descriptors. This is how you take off the training wheels and gain full control over your objects. Imagine a file on your computer. It has content, but it also has attributes: Read-only, Hidden, or System file. JavaScript object properties work the same way. Besides the value, every property has three special "flags" (attributes) that are usually set to true by default: writable: If true, the va…  ( 8 min )

When users struggle with your product, it's easy to assume the problem is with them. Maybe they’re “not tech-savvy” or just didn’t “get it.” But more often than not, the issue isn’t the user, it’s the cognitive effort your product is demanding. In UX terms, this is called cognitive load, and it’s one of the most overlooked reasons why users drop off, get frustrated, or never come back. It’s not loud or obvious, but when it’s high, it quietly sabotages the entire experience. Let’s unpack what it means, how it shows up in real products, and how to design around it. Cognitive load refers to the total amount of mental effort being used in our working memory. Every time someone interacts with a digital product, they’re juggling a few things in their head: What they’re trying to achieve (their g…  ( 10 min )

Web scraping in 2025 sits at an interesting crossroads. Traditional tools are still widely used and capable, but maintaining large scraping pipelines has become more demanding. Layouts change frequently, defensive systems are being improved, and HTML adjustments that break parsers are implemented faster than before. At the same time, AI-driven techniques are maturing. Large language models (LLM) don’t replace the fundamentals of crawling, but they do change how we interpret page content and handle structured extraction. According to a 2025 McKinsey research, companies adopting generative AI jumped from 33% to 71% in a single year. Scraping is one of the areas where this shift was expected. More teams explore web scraping LLM methods and AI data scraping to reduce manual maintenance. GenAI…  ( 10 min )

Introduction Every few months, another major cloud outage makes headlines. AWS us-east-1 goes down, taking half the internet with it. A misconfigured Azure deployment affects thousands of customers. These incidents fuel the multi-cloud narrative: "Don't put all your eggs in one basket." But multi-cloud comes with significant costs—complexity, operational overhead, and often higher expenses. While some organizations genuinely benefit from multi-cloud, many adopt it for the wrong reasons and regret the decision. In this comprehensive guide, we'll explore when multi-cloud makes sense, when it doesn't, and how to implement it successfully if you truly need it. Multi-cloud means using services from multiple cloud providers (AWS, Azure, GCP) for production workloads. It's important to distingu…  ( 14 min )

When building a Python library, the goal is to turn a complex, boilerplate-heavy process (raw API calls) into a simple, elegant one-liner. The FXMacroData API provides real-time macroeconomic indicators for major currency pairs—a goldmine for quant traders and analysts. Raw API calls force developers to repeat code for authentication, error checking, and URL construction. Embracing the DRY (Don't Repeat Yourself) principle, I set out to build a dedicated Python library on top of it, creating a user-friendly wrapper. This article walks you through the core components of that wrapper, covering synchronous and asynchronous clients, proper exception handling, and utility functions. A good library starts with an intuitive entry point. My goal was to turn an HTTP request into a clean Python meth…  ( 8 min )

Why Every DevOps Engineer Should Deploy Their First Portfolio on Killercoda Most DevOps tutorials begin with AWS, GCP, or Kubernetes. But here’s my honest advice: Start with Killercoda’s Ubuntu playground instead. 🔗 https://killercoda.com/playgrounds/scenario/ubuntu I recently deployed my full DevOps portfolio website using nothing but this environment and Nginx — and it was one of the most valuable hands-on exercises I’ve done. Here is the live server running my site: 🔗 https://411913816ee7-10-244-13-238-80.spch.r.killercoda.com/ When you deploy on Killercoda, you learn the fundamentals that cloud providers hide behind fancy panels: creating and securing directories Configuring Nginx from scratch troubleshooting server errors managing processes manually deploying changes without automation crutches It’s the closest experience to running a real Linux server — without paying for one. If you're a beginner DevOps engineer or trying to build confidence: Forget the cloud for a moment. Deploy something raw. Learn the ground truth. Your terminal will become your greatest teacher.  ( 6 min )

There’s something I wish more employers understood — something I didn’t fully have the words for until I lived through it myself: when a developer says the work requires a full-time position, they’re not exaggerating. They’re telling you what it actually takes to build the thing you’re asking for. I learned that lesson from the inside, as the developer whose role didn’t match the expectations placed on it. Stepping into a system built on shaky ground A while back, I joined a small Norwegian company as their only developer. They handled services related to cemeteries and memorials, and they had a system that had grown organically over the years. The database was… let’s say “creatively structured,” and every architectural decision seemed to lean in a different direction. I wanted to do goo…  ( 8 min )

When people report bugs or performance problems, developers need more than logs and metrics; they need context. That’s where debugging and session replay tools enter the picture. These platforms log users' interactions, console logs and network activity, giving teams a window into what really happened before the error occurred. Some popular tools like LogRocket, Sentry, Datadog and FullStory have already established themselves as essential in modern product teams. They give companies the ability to issue track, and this results in better user experiences and the alignment of engineering with design. But a new player in the space, Multiplayer, is betting on developer-first debugging and visibility, which is based around live collaboration, rich context and without any vendor lock-in.

`AI tools today are incredible. But while building real projects with AI, I kept noticing something subtle: It wasn’t a flaw in AI, it was a gap in how we use it. 🧩 The Quiet Problem Developers Face: AI can write code brilliantly. When you’re trying to grow as a developer, you need: And that’s why many developers tell me: “AI helps me code but I still don’t feel confident. Yet guilty or the AI is doing it for me” 🔥 The Question That Led Me to Build PIYE I asked myself: “What if AI could guide me like a mentor, not just assist me like a tool?” Not replacing learning. Something that could: That idea turned into PIYE, an AI mentor built for learning and building together. 🛠️ What PIYE Focuses On PIYE Mentor, Guidance With Clarity: PIYE doesn’t overwhelm you with long answers.

⁠#1 Product of the Day and #1 Developer Tool of the Month: Aikido Security first launched on Product Hunt last month, and they crushed it. Tagline, visual assets, community engagement... Here's a breakdown of what they did right and how to apply it to your launch. Full disclosure: If this was Aikido's first launch on Product Hunt, the team does have previous launch experiences. In fact, they launched Opengrep last February and ranked #5 Product of the Day. Nailed the tagline. The most important part of a launch? These 60 characters are the first thing you read on the front page. "Secure everything you build, host, and run." Simple, relatable, straight-to-the-point. Polished the visual assets. Underrated: The image gallery. It tells your story, visually. It starts with an intro, i.e. the OG image. IMHO It should finish with an end, i.e. your call-to-action. Nailed it. Engaged with the community. They added a first, short comment to get the discussion started. They also upvoted and replied to every comment.

The Foundation: What is a Large Language Model? At its heart, a Large Language Model (LLM) is a type of artificial intelligence designed to understand, generate, and interact with human text. The "large" in its name is no exaggeration. These models are built on neural networks containing billions, or even trillions, of parameters. Think of these parameters as the knobs and dials the model can tune to learn the intricate patterns of language. The real breakthrough that enabled modern LLMs like ChatGPT was the invention of the "Transformer" architecture in 2017. Before the Transformer, AI models struggled with understanding long-range context in text. They might forget the beginning of a long paragraph by the time they reached the end. The Transformer's secret weapon is a mechanism called…  ( 9 min )

A SIP calculator is one of the easiest tools for understanding how much your investments can grow over time. Whether you invest every month through SIP or put in money once through a lumpsum, the calculator shows how your money compounds, how much wealth you can build, and what your final maturity amount may look like. A lot of people assume SIP and mutual funds are the same thing, but SIP is simply a method of investing in mutual funds. You can either invest regularly (SIP) or put everything at once (lumpsum). In both cases, a SIP calculator or mutual fund calculator helps you estimate how your investments will perform in the future. A SIP calculator is a digital tool that tells you how much return you can expect when investing through SIP. You enter three simple inputs: Your SIP amount (…  ( 9 min )

Pt I: Read Here Il existe une réalité que beaucoup évitent d’aborder : malgré nos prières, notre humanisme, notre compassion naturelle… le sort général de nos vies ne semble pas toujours refléter nos efforts ou notre foi. Dieu est-Il injuste ? Est-Il silencieux ? Ou n’existe-t-Il tout simplement pas ? Pourtant, dans le même monde, dans les mêmes villes, dans les mêmes familles, on voit aussi des choses impossibles à expliquer autrement que par une force extérieure. Mais le contraste fait mal : Est-ce une injustice ? Est-ce un prix qu’on paie ? Un mystère ? La réincarnation ? Personnellement, je reste convaincu que Dieu existe. “Car mes pensées ne sont pas vos pensées, et mes voies ne sont pas vos voies.” Ésaïe 55:8 Et c’est peut-être là toute la tension : On doit quand même admettre quelque chose : Mais cela révèle aussi une vérité fondamentale : On est là pour quelque chose qui nous dépasse. La Bible dit d’ailleurs : “Tout est permis, mais tout n’est pas utile.” 1 Corinthiens 10:23 Comme pour rappeler que oui, Dieu nous laisse libres, mais que cette liberté s’inscrit dans une histoire plus vaste. Quant à la souffrance… la question reste ouverte. Alors vivons. Parce qu’au final, malgré le silence apparent, “Je suis avec vous tous les jours.” Matthieu 28:20 C’est peut-être ça, notre véritable espoir.  ( 7 min )

Late 2022. I still remember the excitement. I pulled my classmate aside, opened my laptop, and typed a prompt into this new thing called ChatGPT. When the text streamed back, eyes widened. It felt like magic. It felt like the future. Back then, my message to everyone was simple "You guys need to try this. It's cool. It's going to change everything." Fast forward to Saturday, November 1 (Late 2025). I was standing in front of 70+ people at the Soedirman Digital School event with Purwokerto Dev. I was still talking about AI.

Writing clean code rarely causes burnout. The real culprit is the cognitive load of context switching, managing infinite dependencies, and putting out infrastructure fires while trying to ship features. In 2025, 78% of senior engineers report feeling overwhelmed by operational complexity rather than algorithmic challenges. Multi-agent orchestration changes this dynamic by treating AI not just as a chatbot, but as a specialized team. By assigning specific roles—like tester, debugger, and documenter—to autonomous agents, developers regain the focus required for deep work. The role of a software engineer has mutated. It no longer involves just writing functions; it involves wrangling Kubernetes configurations, securing API endpoints, and managing cloud resources. A 2025 State of DevOps report…  ( 11 min )

For a long time, “frontend” sounded like a thin layer of buttons and CSS on top of the “real” application. Today, that picture is completely broken. Frontend is where product decisions surface, where performance is felt, and where user psychology either works for you or against you. All of that is happening inside a single render cycle. When someone taps a button or loads a page, they are judging not just your design but your product, your engineering, and your understanding of their needs. That is why the biggest upgrade for modern frontend developers is not learning yet another framework. The real shift is learning to think in systems.

We've all heard that "high cohesion" is good. But what does cohesion actually mean? Most definitions focus on the mechanics: "elements that belong together should be grouped together." But this raises the question: how do we know what "belongs together"? The answer lies in understanding cohesion as a knowledge organization principle. Here's a more fundamental way to think about cohesion: Cohesion is about grouping knowledge that changes for the same reason Knowledge that varies together should be grouped together. Knowledge that varies independently should be separated. When you have high cohesion, all the knowledge in a unit changes for one reason—driven by one change driver. When you have low cohesion, the knowledge in a unit changes for multiple independent reasons—driven by different, …  ( 12 min )

In Part 3 of this series, we enhanced our AI agent with domain-specific knowledge through RAG, allowing it to answer questions based on company documents. However, we discovered another critical limitation: when asked about real-time information like weather forecasts or current dates, the agent couldn't provide accurate answers. AI models are trained on historical data with a knowledge cutoff date. They don't have access to real-time information like current weather, today's date, live flight prices, or currency exchange rates. This makes them unable to help with time-sensitive tasks that require up-to-date information. In this post, we'll add tool calling (also known as function calling) to our AI agent, allowing it to access real-time information and take actions by calling external API…  ( 12 min )

AI Agent Memory: From Manual Implementation to Mem0 to AWS AgentCORE Introduction AI agents need memory to remember past conversations, user preferences, and learned information. Just like humans have different types of memory (short-term, long-term, episodic), AI agents use different memory systems to function effectively. This guide explains memory in simple terms and shows you how to implement it both without external tools (using pure Python) and with external tools (using specialized services). We'll end with a complete end-to-end solution using Mem0 that combines all memory types.

Which of the following do you think is faster? direct DOM API calls (createElement, appendChild) assigning HTML strings to innerHTML Chances are you'll say the former is faster and most people would agree. Now, critical thinking to the rescue. Is this really, really true? At the end of the day, browsers have been optimised around parsing HTML for decades and writing HTML feels better than the raw DOM API, so... true or not, is is worth it at all? Thought it's time to test assumptions and hypotheses, both in extreme and more realistic scenarios. An extreme scenario is one where you render a view tens of thousands of times on a page. In a realistic scenario, you render a view once. Two simple functions on the scene. One builds the view by hand with createElement, setAttribute, appendChild…  ( 8 min )

In the high-speed, high-stakes world of modern development, a professional’s worth is measured by two inseparable metrics: the depth of their technical skill and the breadth of their public trust. It is a paradox of the digital age that the very transformation making us better technically (the shift from coder to engineer) must be validated by transparent, human feedback (public review platforms). My name is Simon Leigh, and as the Director of Pure Reputation, I spend my professional life at the intersection of expertise and trust.

TypeScript’s structural type system is convenient and flexible: two types are compatible when their shapes match. That convenience can become a problem when you want different domain concepts (e.g. UserId vs ProductId) to be treated as distinct even though both are plain strings or numbers. This post explains two effective patterns for making types nominal-like in TypeScript: branding (tagged types) and the unique property pattern (using unique symbol). You’ll get practical code, runtime-friendly factories and guards, and guidance about trade-offs and pitfalls. Example of the problem: type UserId = string; type ProductId = string; function getUser(id: UserId) { /* ... */ } const pid: ProductId = "p-123"; getUser(pid); // allowed — but this is probably a bug Because UserId and ProductId …  ( 9 min )

Introduction In modern backend engineering, API integrations are no longer “extra features”, they are the backbone of how systems communicate, automate, and scale. Whether you’re building a fintech product, a logistics platform, a telecom service, or a healthcare system, your application will eventually depend on external APIs for mission-critical operations. The challenge is that most engineers approach integrations as simple HTTP calls. In reality, designing reliable, secure, high-performance integrations requires thinking in terms of architecture, failure modes, resilience, abstraction layers, and long-term maintainability. In this breakdown, I explain API integrations the same way I would coach a backend engineer joining a large-scale engineering team. The goal is to shift your minds…  ( 9 min )

Modern Haima engines include advanced electronic throttle control and multi‑point fuel injection systems optimized for low‑speed torque and emission efficiency. In daily repair operations, these systems often show calibration drift after 60,000 km due to sensor hysteresis and aged ignition maps. During the last months at our workshop in Tehran we observed several Haima repair shop units with inconsistent idle speed caused by slight mismatch between IAC stepper control and ECU baseline airflow table. Many technicians replace actuators before examining the adaptive fuel trims. But on Haima engines, the real issue often lies in the temporal alignment between throttle opening rate and manifold pressure transient. Using only an OBD snapshot isn’t enough — data logging under dynamic load (i.e., simulated hill climb) gives more reliable insights. The most stable correction we found was clearing the long‑term fuel trim (LTFT) values, running the idle learning cycle, and re‑mapping the ignition advance using a scanner that supports GDI adaptive tables. This can recover up to 5–8 % of lost efficiency. From a thermal standpoint, Haima’s radiator core is small relative to engine bay volume, which increases localized heat stress at the throttle body zone. Regular coolant replacement with G12++ improves the actuator’s life‑cycle notably. ⚙️ Engineering note: ECU synchronization and thermal equilibrium are inseparable in modern Haima vehicles; diagnostics should always consider both software behavior and heat‑transfer equilibrium rather than component isolation. Written from field observations as part of engine system diagnostics training in Tehran.  ( 6 min )

I love programming and after exploring cloud and devops, I was almost giving up but terraform is sparking my interest again. I think I’m one of the few people who actually enjoy a formal introduction to things. Today was my official introduction to Terraform. I explored why Terraform exists, the problems it solves, the old-school way people used to interact with cloud platforms, and why Infrastructure as Code matters in modern engineering. If Terraform or IaC still sound new to you, here’s the simplest update: Infrastructure as Code is a way to create cloud resources using code instead of clicking around dashboards. Terraform is the most popular tool for this, letting you describe the infrastructure you want and then letting Terraform talk to the cloud provider on your behalf. Get started …  ( 7 min )

I've been building on AWS for multiple years now, and one of the most repetitive parts I found was writing crude operations for DynamoDB. Every project starts the same: use boto3 to define the table define a big JSON payload JUST to fetch some data from the table copy-and-paste methods from previous projects for all CRUD operations, basically adding boilerplate code That's when I found out about a library called PynamoDB , a lightweight ORM for DynamoDB tables and that changed the way I manipulate table’s data.

If you're an engineer, you've likely been there: you receive an email from the VPE. "Our cloud burn rate is up 15% this quarter. Find the leak." Suddenly, you’re spending a week digging through Cost Explorer when you should be shipping features. This reactive loop is a system failure. The cost of an S3 bucket or an undersized Redis cluster isn't hidden; it's just hidden from the people making the deployment choices (the developers). The Solution: Move Cost Awareness to the Merge Request. Step 1: The Cost Budget Function The trick is to connect that plan to a cost estimator. Tools like Infracost or Terragrunt hooks can parse the plan output and give you a dollar estimate for new/modified resources. What we're looking for: A 'cost_impact_monthly' variable that appears for every single PR modifying infrastructure. Step 2: Implementing the CI/CD Gatekeeper We define two simple rules in our CI pipeline (e.g., GitHub Actions, GitLab CI): Low Impact Threshold (Green Path): If cost_impact_monthly is $100 (or $500, define your risk tolerance), fail the pipeline and require a specific /cost-approved comment from an Engineering Manager (or FinOps role) to proceed. This is the non-obvious shift: The friction is applied only when the financial risk is high. This makes the Engineering Manager the conscious gatekeeper for major spending, while preserving developer flow for minor changes. The Outcome: From Audit to Prevention By treating cloud spend as an observable artifact of the deployment pipeline, we turn a quarterly audit problem into a daily prevention system. Developers become cost-aware by default, and your VPE stops sending those embarrassing emails. You’ve successfully made the cheap way the easiest way to ship  ( 7 min )

Background I understand why you might dislike DEI... I understand why some of you might have reservations about DEI. It's partly due to the disruptive actions of some radical minorities. The recent move to abolish DEI in the U.S. is fresh in memory, and there may be engineers who inwardly applauded this decision. In fact, some tech companies have removed mentions of DEI from their websites. From the standpoint of a Knowledge Architect, I must say that DEI is actually crucial for engineers.

Problem Definition Ordering log events produced across distributed systems is fundamentally constrained by the nature of independent physical clocks. Wall-clock timestamps cannot provide a reliable global sequence, because each machine maintains its own oscillator with unavoidable drift. Even under NTP or similar protocols, timestamp discrepancies accumulate continuously due to rate differences, network delays, and local scheduling effects. Any distributed operation introduces uncertainty in temporal order. Network latency, buffering, batching, and concurrency all contribute to the inability to determine whether two events across services occurred in a particular order when relying solely on physical time. The concept of temporal ordering is meaningful only within a single clock domain; …  ( 7 min )

The moment I realized “latest” is a trap When I first started using Docker, I thought: “Ah, just push it with latest.

The modern web is a battlefield. Between SQL injection attempts, automated credential stuffing, aggressive scrapers, and waves of bot traffic, every public-facing site is exposed to constant threats. To keep applications safe, developers and sysadmins have long relied on Web Application Firewalls (WAFs). Most teams default to cloud WAFs — offerings like Cloudflare, AWS WAF, or Akamai. They’re convenient and quick to deploy, but sometimes you need more than convenience. Maybe you need full control over traffic, maybe privacy regulations prevent you from routing data through third-party networks, or maybe the long-term subscription cost isn't appealing. That’s where self-hosted WAFs step in. And among the new generation of self-hosted solutions, SafeLine has been gaining traction for taking…  ( 8 min )

In many organizations, fax has quietly transformed from a loud, paper-driven chore into a silent digital backbone for secure, compliant communication. This evolution is not just about replacing machines; it is about redesigning how information flows through critical workflows across the healthcare, finance, legal, and government sectors. Traditional faxing chained teams to physical devices, manual dialing, paper jams, and filing cabinets, slowing down approvals and increasing the risk of misplaced or exposed documents. Digital fax platforms shift this work into the cloud, providing centralized control over transmissions, storage, and routing so that documents move quickly while remaining auditable and secure. Instead of printing and scanning, users send documents directly from core app…  ( 8 min )

The "hello world" phase of generative ai development is officially over. We have moved past the era where simply calling an OpenAI API was enough to impress stakeholders. As we settle into 2025, the focus for software engineers has shifted entirely from experimentation to reliability, observability, and cost-efficient scaling. Building production-grade generative systems requires a rigorous engineering mindset. It is no longer just about prompt engineering; it is about architectural patterns that ensure determinism in a non-deterministic environment. The most significant trend we are seeing is the move away from monolithic LLM calls toward compound systems. In professional generative ai development, reliance on a single model's raw output is often a recipe for hallucination and latency. In…  ( 7 min )

This is where AI-powered recruiting is stepping in as a game-changer. With advances in automation, predictive analytics, and conversational AI, organizations are finally gaining tools that help remove bias, widen talent pools, and create a more equitable hiring experience for every candidate.

Traditional recruitment heavily depends on human judgment, which can unintentionally favor certain backgrounds, education levels, appearances, or …  ( 9 min )

Today marks the exciting start of the #30daysofawsterraform challenge with @piyush Sachdeva, and Day 01 immediately tackled the most critical question in modern cloud engineering: Why do we need Infrastructure as Code (IaC)? The key takeaway is that relying on the cloud console for infrastructure management is a recipe for scaling issues, high costs, and system inconsistencies. Our goal is to move from manual clicks to automated, version-controlled code. The Core Problem: Manual Cloud Operations Don't Scale Using the cloud console (GUI) might seem easy for creating a single resource, but complexity quickly leads to disaster in a production environment. Imagine provisioning a complex three-tier application. This involves setting up the Virtual Private Cloud (VPC), multiple servers (EC2), lo…  ( 8 min )

Chapter 2: Variables, Types, and the Art of Declaration The morning light streaming through the tall windows of the Whitmore Archive had a different quality today—sharper, more purposeful. Ethan arrived precisely at ten, as Eleanor had suggested, carrying two cups of coffee in a cardboard tray. The aroma of single-origin Ethiopian beans preceded him down the stairs. Eleanor looked up from her desk, one eyebrow raised in approval. "Bluestone Lane?" "They remembered you from yesterday," Ethan said, setting her cup down carefully. "The barista said 'the usual for the elegant woman who knows her coffee.'" "I may have been going there since 1994." Eleanor lifted the cup and inhaled. "Perfect. Now sit.

Il m’arrive souvent, entre deux lignes de code, deux features à shipper ou deux idées de startup; de repenser à l’environnement dans lequel j’ai grandi. Un environnement qui, qu’on le veuille ou non, influence profondément notre manière de travailler, de penser, de créer et même de rêver. En RDC, beaucoup de gens ont vécu des situations qu’on aurait du mal à imaginer dans un pays “normal”. Des injustices tellement profondes qu’elles laissent des traces invisibles. Grandir dans ce contexte, ce n’est pas juste vivre. Je vois des jeunes déjà épuisés psychologiquement alors qu’ils n’ont même pas commencé leur vie. Le contraste le plus cruel ? Alors oui, changer sera difficile. Et pourtant, malgré tout ça, il existe une lueur. Peut-être que notre rôle, à nous, c’est d’allumer une lumière. Ce n’est pas un article technique. C’est juste… un rappel. Une pensée.

Most people think running AI coding models locally is confusing, slow, and not worth it—here's the simple playbook for private, fast dev that works ↓ You don't need the cloud to ship faster. You need control, privacy, and zero surprise bills. I learned this after testing seven open models on a normal laptop. Local wins when latency, security, and cost matter. Your code never leaves your machine, so risk drops fast. Tokens are free after setup, so usage can scale without panic. Modern 15B–70B models handle code assist, tests, and docs well. Example. On a 16GB RAM laptop with a 15B model, code completions arrived in 0.9 seconds on average. Unit tests generated in eight seconds per file. We cut review time by 32 percent and saved 400 dollars a month in API fees. Setup took 45 minutes using a container and a GPU driver. ↓ A simple way to get started this week. ↳ Pick a model sized to your hardware, start with 7B–15B if you have a single 8–12GB GPU. ↳ Use a local server like Ollama or LM Studio to run and manage models. ↳ Connect your IDE through an API or extension for inline suggestions. ↳ Cache prompts, pre-load repos, and run the model in 4-bit to boost speed. ↳ Track latency and acceptance rate so you improve what actually matters. Expect instant responses, predictable costs, and fewer red flags from security. Your team ships faster because feedback loops shrink to seconds. What's stopping you from going local for coding today?  ( 7 min )

With generative AI and coding agents, we're producing code at unprecedented speed while accumulating dependencies to match. Evidence now shows AI doesn't just suggest dependencies: it hallucinates ones that don't exist. In this case, a package called "huggingface-cli" was downloaded thousands of times, including by teams at Alibaba, before anyone realized it was completely fictitious. Each hallucinated package name becomes a supply chain vulnerability waiting to be exploited, with attackers racing to register them before developers discover the mistake. But hallucinations are just one risk in this acceleration of code generation. Even with legitimate packages, the speed creates problems. In the past, platform and security teams could influence dependency choices through documentation, appr…  ( 8 min )

In this article, we will explore Redis from the ground up—its architecture, data structures, use cases, persistence options, scalability, and best practices. By the end, you will understand why Redis is one of the most trusted technologies in production environments around the world. Redis (REmote DIctionary Server) is an in-memory key–value data store that supports powerful data structures and extremely low-latency operations. Unlike traditional databases that rely heavily on disk I/O, Redis keeps data in RAM, making it exceptionally fast. Redis …  ( 8 min )

How We Built Ad Injection That Users Actually Appreciate: Meet Monetzly In the fast-paced world of AI application development, monetization often feels like a daunting challenge. Developers want to focus on creating innovative solutions, but the pressure to generate revenue can lead to disruptive user experiences. Enter Monetzly—the first platform where developers can both monetize their AI apps and earn from hosting relevant ads, all while maintaining a seamless user experience. As AI applications explode in popularity, many developers find themselves asking: How can I monetize my app without compromising the user experience? Traditional methods, like subscriptions or paywalls, can alienate users, leading to higher churn rates. At Monetzly, we’ve engineered a dual-earning platform tha…  ( 7 min )

Organizations adopting LLMs at scale often struggle with fragmented API usage, inconsistent authentication methods, and lack of visibility across teams. Tools like Gemini CLI make local development easier, but they also introduce governance challenges—especially when authentication silently bypasses centralized gateways. In this article, I walk through how to route Gemini CLI traffic through LiteLLM Proxy, explain why this configuration matters for enterprise environments, and highlight key operational considerations learned from hands-on testing. Before diving into configuration, it’s worth clarifying why an LLM gateway is needed in the first place. If developers run Gemini CLI with default settings: Authentication may fall back to Google Account login → usage disappears from organization…  ( 8 min )

AI's impact on white-collar jobs and layoffs is reshaping office life in palpable ways. Picture an open plan office where rows of cubicles blur into streams of code and dashboards. Algorithms flag redundant tasks and digital assistants draft reports in seconds. As a result, middle-management spreadsheets shrink and hiring plans face harsh review. Many knowledge workers now share their schedules with chatbots and automation routines. However, this shift does not erase human judgment or creativity. Instead, teams reorganize around strategy, empathy, and complex problem solving. Because AI handles data-heavy chores, roles focused on nuance gain value. But layoffs follow where firms chase efficiency without reskilling staff. Therefore managers must act quickly to retrain employees and redesign…  ( 15 min )

HTTP vs HTTPS vs TCP vs UDP: Finally Understand The Difference! 🏗️ If you've ever felt confused about these four acronyms that rule the internet, you're not alone. Most explanations get stuck in technical jargon, but today I'll give you a mental model that will make everything click forever. Here's the analogy that changes everything: This is the TRANSPORT LAYER - it decides HOW data moves between systems. TCP = Moving Truck (reliable, ordered, confirms delivery) UDP = Bike Messenger (fast, no guarantees, fire-and-forget) Why it comes first: Everything else gets built on top of this foundation. This is the APPLICATION LAYER - it defines WHAT the data means and how applications talk. HTTP = Open Floor Plan (everything visible, no security) HTTPS = Fortified Rooms (encrypted, secure, auth…  ( 8 min )

Sometimes it feels like building software isn’t the hard part — rebuilding the same integrations over and over is. Every time I started a new project, I found myself: Searching for the same API docs Copy-pasting an old webhook handler Debugging the same auth flow Fixing missing env variables Rewriting the same config boilerplate None of it moved the project forward. It was just the tax you paid before the real work began. So I asked myself: "Why isn't there a reusable, production-ready playground of integrations for Next.js?" There wasn’t — so I built one. One place to grab verified real-world integrations Webhooks already implemented and tested Verified auth flows TypeScript-first patterns Examples that matched how modern Next.js apps are built Not tutorials. Not copy-paste snippets. Actual working building blocks. That’s what became Integrate API — a toolkit plus a Chrome extension that helps you ship integrations fast, without guessing. It now includes integrations for: Stripe Supabase SendGrid Liveblocks Meilisearch UploadThing And 10 more This saves time — and honestly sanity. If you're curious: 👉 https://integrateapi.io Would you want a feature like "generate integration per project type"? I’m exploring it — curious what devs think.  ( 6 min )

The story of modern frontend frameworks has always revolved around change — how to detect it, represent it, and respond to it efficiently. React built its entire philosophy on a simple but powerful assumption: Changes in data and component state are unpredictable. To cope with this uncertainty, React introduced the Virtual DOM — But this design, while revolutionary in 2013, also came with a price. So here’s a question worth asking: What if that assumption was wrong? That’s the core idea behind Signals and Fine-grained Reactivity — This philosophy echoes what Ryan Carniato, the creator of Solid.js, often calls “reactivity without illusion.” In this 30-part series, we’ll dive deep into the mechanics, architecture, and design philosophy of Signals and fine-grained reactivity. Along the way, we’ll compare how frameworks like React, Vue, and Solid handle reactivity differently, This series is inspired by my open-source project, segnale-react, By the end of this journey, you’ll understand not just how Signals work, The next article begins right at the core — Stay tuned.  ( 7 min )

Forget the hype train. If you want to create videos that actually tell a story, you need to stop waiting for Sora and start using Textideo. I have a confession to make. For the last six months, I’ve been suffering from "AI Fatigue." You know the feeling. Every morning, you open X (formerly Twitter) and see another mind-blowing demo. An astronaut swimming in coffee.

CSS has come a long way from being a simple tool for styling text and backgrounds. Today, it’s a powerful language that supports built-in functions, allowing you to perform calculations, reuse values, manipulate colors, and even adapt designs based on context — all without JavaScript. In this post, let’s explore some of the most useful CSS functions and how they can transform the way you write styles. Just as functions in programming languages make code more dynamic, CSS functions let you generate and compute values on the fly. They can: Keep styles flexible and responsive Eliminate repetitive hard-coded values Enable theme switching and runtime adjustments Improve maintainability by avoiding “magic numbers” The calc() function allows arithmetic operations (+, -, *, /) directly in CSS. css…  ( 8 min )

As developers, we’re no strangers to the tradeoffs between 3D reconstruction quality, speed, and accessibility.

The horse half died by the time we came off the highland. That's why I don't name my horses. My boots had holes. My six was dry. Nothing in my pockets but metadata.

Amazingly hard to use well for any sizable project, let alone the enterprise. Same with the other cloud providers. Metadata is supposed to drive everything, ideally from metadata catalogs.

Erase and Rewind: Surgically Removing Bias from AI Models Imagine your groundbreaking AI, trained on a massive dataset, suddenly exhibits unwanted biases – perhaps discriminating against a specific demographic. Retraining from scratch is a time-consuming and expensive nightmare. But what if you could surgically remove the problematic data's influence, leaving the rest of your model intact? The key is understanding how that specific data subtly warped the model's learning landscape. Geometric-Disentanglement Unlearning (GDU) is a technique that treats model updates as movements in a high-dimensional space. The core idea is to decompose the desired "forgetting" update into two components: one that affects the retained knowledge and one that doesn't. We surgically apply only the component o…  ( 7 min )

After receiving the Top Docker Author badge last week for my Offline AI post (thanks everyone! 🙏), many of you asked about my workflow for hardware and vehicle networks. So today, I'm switching gears from AI to Heavy Duty Vehicles. If you work with CAN Bus or SAE J1939 (Trucks, Buses, Machinery), you know the pain: Professional tools are expensive: A Vector CANalyzer license costs thousands of dollars. Hex dumps are unreadable: Seeing 18FEF100 means nothing unless you memorize the J1939 spec. Hardware dependency: You usually need a physical adapter (PCAN, Kvaser) just to test your code. To solve this, I built a Python-based J1939 Sniffer that decodes PGNs automatically and includes a Simulation Mode for hardware-free development. Standard CAN (11-bit) is simple.

Nicole Forsgren just dropped a new book, and I absolutely CONSUMED it. It's called Frictionless: seven steps to help engineering teams move faster in the age of AI. Forsgren created DORA. She created SPACE. She wrote Accelerate, the book that fundamentally changed how we measure engineering performance. When Forsgren talks about engineering velocity, you listen. And, I hope I'm not oversimplifying, but my biggest take away is that "Most productivity metrics are systematically misleading." Lines of code? Blown away by AI. Deployment frequency? Useful for assessing pipeline health, but disconnected from whether your team is building the right things. Her three pillars of developer experience: And this resonates with me deeply.

So I thought, what if I put that in a loop where every tool call could return a completely new configuration for the request? It works like this. Note there are two configurations: xai and oai. xai is instructed to play dumb and try to answer 42, oai is instructed to write haikus. xai is only promoted to oai once it gets the right answer. import complete from './complete.js'; let tap = x => (console.log(x), x); async function looptools(init) { while (true) { let res = await complete(init.logs, { ...init, logs: undefined }); let tools = [...Object.entries(res.tools || {})]; if (tools.length && t…  ( 7 min )

If a core developer wanted to work on one specific part of the WordPress codebase, it wouldn’t be safe or efficient to have them directly edit the “official” source code. Instead, version control lets developers safely work through branching and merging. With branching, a developer duplicates part of the source code (called the repository). The developer can then safely make changes to that part of the code without affecting the rest of the project. Then, once…  ( 12 min )

Throughout my career, I've encountered array chunking in everything from pagination systems to batch processing jobs. What seems simple at first glance hides tricky edge cases that can silently corrupt your data—like out-of-bounds errors or inconsistent chunk sizes. Today, I'm going to show you my battle-tested algorithm for chunking arrays in Go—one that handles all those edge cases cleanly. Write a function that takes an array and a chunk size as input. The function should return a new array where the original array is split into chunk of the specific size.

Hiring managers operate under load. They scan for the smallest number of signals that predict whether you’ll remove friction instead of adding it. Everything else is noise. Rebuild your materials around that reality. Expose your reasoning process. Most candidates describe tasks; the ones who get hired describe tradeoffs. Show how you selected one approach while discarding alternatives. Show what you optimized for. Show what you intentionally ignored. This proves decision-making under scarcity, which is the actual job. Remove ambiguous claims. Replace “improved performance” with the exact metric. Replace “worked on APIs” with the exact failure point you corrected. Ambiguity signals inexperience. Specificity signals operational maturity. Consolidate everything into a single through-line: you compress time-to-output. That’s the trait that stands out in a stack of interchangeable resumes.  ( 6 min )

The Motivation As developers, we often need a quick way to host an image for a PR, a README, or a StackOverflow question. But most free image hosts are either slow, riddled with ads, or require a signup. I wanted to build something better—something that follows the Unix philosophy: Do one thing, and do it well. Meet ImgPeek. 👉 imgpeek.com ImgPeek is built with performance, simplicity, and low cost in mind: Frontend: Vue 3 + Vite (snappy SPA experience) Storage: Cloudflare R2 (S3-compatible — zero egress fees) Backend Logic: Cloudflare Workers (TypeScript) All image processing happens directly in the browser using the Canvas API and modern compression algorithms. Compression: Images are compressed before upload to save bandwidth Resizing & Conversion: Fully client-side—raw photos never hit the server unless you're uploading them 2. Direct R2 Uploads To keep the backend simple and cost-efficient, the client requests a Presigned URL from a Cloudflare Worker.

🗂️ 1. The Folder Structure AppName/ Features folder = clean separation Each feature contains: View ViewModel Subcomponents Logic specific to that feature No giant files. No spaghetti. Services are abstracted Every service has: a protocol a live implementation optionally a mock Makes testing way easier: protocol AudioServiceProtocol { func play(_ file: String) func stopAll() } ✔ Design system lives in one place Your app finally feels consistent. ✔ Resources are not mixed with logic ✔ Support folder stores non-shipping dev files 🧩 Workflow Tips Use extension files sparingly Don’t put every modifier and helper in one huge file. Instead create: mathematica Use folders, not groups Keep feature folders self-contained If a feature can't stand alone → it’s not modular enough. 🚀 Final Thoughts scale apps faster onboard contributors easily debug without hunting files avoid “junk drawer” folders  ( 6 min )

Solves the "energy problem" in thermodynamics by addressing insufficient energy extraction from systems through efficient journey optimization.

Warp space-time via a "bubble" (phenomenological/ontological lensing bubble—unpoppable, multi-lensing).

========================================================================== Most .NET developers grow up on classic N‑Tier or Clean / Hexagonal architectures: Presentation layer Application / Services layer Domain Data access Each layer is neatly stacked… but a single feature like "Get weather forecasts" ends up scattered across controllers, services, repositories, DTO folders, validators, and view‑models. Vertical Slice Architecture (VSA) turns that on its head. Instead of organizing code by technical layer, you organize it by feature. Each feature owns everything it needs — from the HTTP endpoint down to the data access — in one cohesive folder or slice.

AWS announced multi-attribute composite keys for DynamoDB global secondary indexes on November 19th. That's a lot of words, but what does it actually mean? It means it's easier to pull data out of DynamoDB in ways you hadn't planned initially, without a bunch of extra work. To fully explain why, I need to explain keys in DynamoDB. I'll assume you know that DynamoDB is a NoSQL database, that the "database" is called a table, and the table is a collection of items, which you can think of as records or rows. You'll hear many names used for different keys in DynamoDB. It all makes sense, but it can be confusing. Every item in your table has a primary key, as you are probably used to with relational databases such as MySQL, PostgreSQL, Microsoft SQL Server, Oracle, and many others. That primary…  ( 12 min )

Let me preface this by saying that there is no clear-cut winner and no single "best" solution. Multiple solutions stand out to me as feature-rich, and each has its own philosophy. We can never say that there is the best architectural library you should use, because it all depends on the team's needs. I would suggest always picking the best technical solution for the business needs and not the other way around - i.e. don't optimize for newness, cool tech, capabilities, or your intrinsic interest in some technology. The business and team needs should always be the driving factor for choosing a technical solution. Over the years, whenever I was faced with a decision to choose a particular dependency, I felt there was no "single source of truth" that compared as many libraries and solutions as…  ( 26 min )

Why You’ll Never Build a Strong Model with the 9 Raw Features of the California Housing Dataset (6 Key Insights) A 5-minute analysis of the California housing dataset A while back, I reopened the famous California housing dataset and looked at it from scratch — no solutions, no notebooks, just the raw data and my own eyes. 'longitude', 'latitude', 'housing_median_age', 'total_rooms', 'total_bedrooms', 'population', 'households', 'median_income', 'ocean_proximity' Here are the six things that actually matter (and that most people miss): Latitude and longitude alone tell you almost nothing. Any single coordinate has a massive spread in prices — you can’t rely on them as-is. Median house age has the same issue: huge variance at every age level. By itself, it barely helps the model.

We romanticize big engineering wins. The performance chart that hockey-sticks up. The keynote slide with the impossible number. The "we hit a billion requests per second" humble brag. The truth behind those moments is never one big breakthrough. It's dozens, possibly even hundreds, of small changes and enhancements. The kind that look ordinary when they land in a PR. The kind that your eyes casually skip over in release notes. The kind nobody celebrates… until they compound into something revolutionary. I was recently reminded of this while listening to the Cache It podcast. Valkey project maintainer Harkrishn Patro described how his team scaled their system to handle a billion requests per second.

We often hear that communication is critical. The trend of returning to the office is resurging. But as an engineer, I find myself wondering, "Is this really okay?" Our true calling is engineering. Engineering is creative, and creativity requires solitude and silence. Yet, what is our reality? We are compelled to commute to the office, expected to participate in meetings, and still rely heavily on chat—that 30-year-old technology—for most of our text communications. Don't get me wrong, I'm not advocating for brilliant jerks, but I'm also fed up with emotional labor. I am an engineer and want to fully commit to engineering. I'm not here to provide customer service to colleagues or clients, nor do I wish to build relationships. Okay, maybe this sounds a bit selfish. Let me rephrase that. It's not about what I "want" to do; it's about what I "should" do. Listen, customer service and relationship building are merely tools. I'll engage in them if necessary, but they should never be the main focus. Engineering should be the main focus because it's something only we engineers can do. Engineering, by nature, is a creative endeavor—it's not easy. It's not something that can be accomplished by those who are distracted by superficial relationship-building. Recently, I've felt that generative AI is a positive trend. It seems like the wave of asynchronous text communication is making a small comeback. I hope we can eventually manage asynchronous text communication with humans as well. There's no need for us to return to the office or hold meetings, right? While it might be necessary for some amateurs in engineering, we have the capability to handle things through asynchronous text communication. What do you all think? Personally, I'm completely done with emotional labor!  ( 7 min )

There’s a moment every developer knows: the spark of a new idea, the itch to start building, and the friction that follows. Setting up a clean Laravel environment, wiring in tools, installing dependencies, crafting a sane directory structure, writing boilerplate steering documents… the overhead adds up. It’s enough to take the shine off that early momentum. I’ve been building Laravel apps with Kiro for a while now, and something clicked along the way. Every time I tightened up my steering documents, the generated Laravel code looked cleaner and I built faster. Eventually it hit me that all this polish should live in a reusable template instead of in my one off projects. If the foundation was solid from the start, most of the usual setup time just vanished.

Mastering Both In-House Production and Introspection What is In-House Production? In-house production refers to creating software or concepts within your own organization. By relying on in-house production, communication costs can be minimized as everything is completed within the organization without the need to outsource. Naturally, this approach allows for an easier reflection of the company's domain knowledge. Challenges like domain-driven development become less burdensome. Even if the company does not have its own developers, it's often more cost-effective to train them internally rather than outsourcing. Introspection involves reflecting on oneself independently. Through introspection, you can face your current situation and beliefs head-on without neglecting or stiflin…  ( 8 min )

When you need to use multiple Git accounts on the same computer (to simplify for the purpose of this post let's use two accounts that we will call personal and work), you may need Git to automatically use different identities depending on which repository you are working on.

This guide explains how to set up multiple Git accounts, assign each account to a specific directory, and ensure that the correct SSH key and identity are used automatically. Don't define multiple [user] blocks in a single .gitconfig file. Don't use the same SSH keys for different authentications. Do avoid manual git config user.email overrides per repository.

My college data structures course taught new and delete, then handed us assignments that ran for 30 seconds and exited. Memory leaks? Dangling pointers? "Just be careful" was the advice. The assignments ended before the leaks mattered. Those short-lived programs never exposed the problems with manual memory management. A web crawler runs for hours and processes thousands of documents. Miss a si…  ( 12 min )

Tired of fighting with API responses in Angular? Discover how to transform your data handling from a maintenance nightmare to a developer's dream. If you've worked with Angular and APIs, you've likely encountered this familiar frustration: // ❌ The current reality - dumb data containers interface User { id: number; firstName: string; lastName: string; createdAt: string; // Wait, why is this a string? birthDate: string; // And this too? status: string; } // ❌ Business logic scattered everywhere @Component({ template: ` {{ getUserFullName(user) }} {{ isUserActive(user) }} {{ calculateUserAge(user) }} ` }) export class UserComponent { // Why is this logic in my component? getUserFullName(user: User): string { return `${user.fir…  ( 10 min )

I recently had a look at the Chrome MCP server and it looks really cool. So, let me show you a quick example of what it can do. Getting Started First of all, if you don't have it installed yet, there are instructions available. Like every other MCP server, you just need to have somewhere in your client settings the configuration string. { "mcpServers": { "chrome-devtools": { "command": "npx", "args": ["-y", "chrome-devtools-mcp@latest"] } } } I'm using VS Code, which has a command in the CLI for this. You can just open a new terminal, paste the command, and that's basically it. code --add-mcp '{"name":"chrome-devtools","command":"npx","args":["chrome-devtools-mcp@latest"]}' In any case, full instructions are in the Chrome MCP server documentation.

Today I learned how to unpivot a table from a wide format to a long format using the .melt() method. Why did I even need to learn that? Many datasets are commonly represented in wide format but long formatted data is often more accessible for computers to work with hence the need to learn this important concept Trust me to always put into practice any new concept I learn. So for my practice pleasure, I worked with unemployment data that originally had one row per year and 12 separate columns for each month. This format is common in raw economic datasets but not ideal for time-series analysis. So I reshaped it using .melt() to convert the wide table into a long format where each row represents a specific year-month pair. This gives me three clean columns: year, month and unempl_rate. This structure is much better for analysis. Next, I combined year and month into one date column and converted it into an actual datetime object. This is important because time-series models and visualizations rely on having a real date index. I sorted the data by date and plotted unemployment rate over time. This is a core skill in data work, especially in economics and finance. This process allows us to: Learning to reshape and prepare data like this is the foundation of almost every real-world economic analysis. Stay tuned for tomorrow😊 -SP  ( 7 min )

Hey everyone! This is my first public post, so I’m writing with a bit of nervousness — but mostly with real joy that I just want to share, not “promote” anything. I’ve been in web development for many years, and I’ve built so many projects that I’ve honestly lost count. And once again — on a regular day — I decided to create something new. Not because I had to, but because this is my way to relax 🙂 I started working on a series of MCP tools (yes, for Cursor), and the first one I made tackles something that has always been painful for me as a developer: working with images. Optimization, resizing, cropping, aspect ratios, circles, watermarks, placeholders, color palettes… basically all the annoying things that steal your time when you just want to build an interface. In an MVP you need p…  ( 7 min )

With the new capabilities AWS is rolling out, the agent will stream responses in real time as they are generated. Below is a high level diagram representing the target architecture. For this project I will implement a RAG system using serverless services. We can outline the following requirements for a low volume of 1000 requests per month. The system should allow sending messages and receiving a response in real time as it is generated. The system should restrict access …  ( 14 min )

When I left art school, I didn’t expect the world to feel so heavy. People always talk about how freeing it is to walk away from something that isn’t right for you, how bold it is, how brave. But my experience didn’t look like that. Mine looked like packing my supplies into a cardboard box that kept collapsing on the sides, walking out of a building that had once felt like my entire life, and trying not to cry on the train ride home. I thought stepping away would make everything feel lighter. Instead, it felt like I had stepped off a cliff I didn’t know the height of.

When people asked why I left, I never knew how to answer in a way that felt honest. Saying I…  ( 11 min )

Erase Faces, Not Utility: Instant Privacy for Image AI Struggling to share facial image datasets without compromising privacy? Traditional methods like blurring destroy crucial details, crippling downstream AI tasks. What if you could swap identities seamlessly, retaining key attributes like pose and expression? The core idea is simple: navigate a pre-trained image model's 'hidden' space to find and replace the identity component of a face. Think of it like swapping the engine in a car. You keep the chassis (attributes), but the power source (identity) changes instantly. This allows generating entirely new, anonymized faces that maintain the original image's valuable characteristics. This approach differs dramatically from methods that require retraining. Instead, it pinpoints precise 'i…  ( 7 min )

More and more remote workers and freelancers are being paid in cryptocurrency. It’s fast, global, and convenient — until it isn’t. Most everyday expenses — rent, utilities, groceries — are still in euros, creating a growing tension between crypto income and real-world spending. On-Ramps vs Off-Ramps Regulatory Complexity How Fintech Is Responding This growing friction is driving fintech innovation: Crypto-linked debit cards that auto-convert assets to fiat at the point of purchase Hybrid accounts that let users hold crypto while spending euros Payroll services that manage volatility and tax reporting Platforms that simplify movement between crypto and traditional banking Exchanges like Coinbase, WhiteBIT etc are expanding their services to make on/off-ramp operations smoother, reflecting a broader trend: trading platforms are evolving into full-scale financial gateways. Read more about this here Bottom Line The gap between earning crypto and spending fiat is the biggest obstacle to mainstream adoption.

What if you could build production-ready container images for your Python projects without installing Docker, writing Dockerfiles, or dealing with daemon dependencies? That's the vision behind pycontainer-build — a native, Docker-free container image builder for Python.

Animations are often treated as an optional enhancement in mobile apps. Many developers open a Figma file, inspect layout spacing, apply colors, build screens, and move on — without ever thinking about motion. But animations are not decoration. They are communication. They guide attention, improve perceived performance, and make the UI feel natural. Without them, interfaces feel abrupt and lifeless. There are multiple animation libraries in the React Native ecosystem — the built-in Animated API, Moti, LayoutAnimation, and Reanimated. Each works differently and serves different use cases, but in this guide, we’ll focus specifically on the Reanimated library. Animations improve the UX in four major ways: They explain UI changes They reduce perceived waiting time They make transitions smoot…  ( 9 min )

You’ve probably lived this sprint-from-hell before. Product wants “self-serve revenue dashboards.” Sales wants “real-time MRR.” Finance wants “clean numbers by Monday.” You, naturally, get the request at 4:45 p.m. on Friday… and somehow it always ends with yet another CSV export from your app and a forest of spreadsheets on someone’s shared drive. The irony: your product already emits almost everything finance needs. It’s just trapped in logs, databases, and SaaS tools that were never designed to be a single source of truth. This post is about fixing that from the engineering side. Not by becoming an accountant, but by treating finance as another downstream consumer of your event stream—and wiring your app into the finance stack in a way that’s repeatable, testable, and boring enough to tr…  ( 11 min )

For years, fintech was seen as a patchwork of separate services: payment processors here, banking APIs there, crypto exchanges somewhere on the side. Each solved a narrow problem, often without deep integration or a shared architecture. But the industry has quietly crossed a critical threshold — it’s no longer a set of tools. It’s becoming an interconnected digital infrastructure layer, and this shift fundamentally changes the developer’s role in fintech. We’re entering a phase where building financial products looks less like feature development and more like ecosystem engineering. The modern fintech stack increasingly spans payments, identity, compliance automation, real-time risk scoring, blockchain rails, tokenized assets, data streaming, and multi-cloud infrastructure — all operating …  ( 7 min )

What is inheritance: It is the mechanism by which object of one class act as object of another class. Here, one class can inherit the features (fields and methods) of another class. This is one of the fundamental concept in OOPs. A class that inherits from another class can reuse the methods and fields of that class. To inherit from a class, we use the extend keyword. Syntax: class Parent { void display() { System.out.println(" parent class."); } } class Child extends Parent { void show() { System.out.println(" child class."); } } Ex: Here, there are two different classes : ClassRoom class and Student class. public class ClassRoom{ public static void main (String[] args){ ClassRoom cr = new ClassRoom(); cr.learnJava(); } public void learnJava(){ System.out…  ( 7 min )

What is Infrastructure as Code(IaC)? why this matters: It keeps your infrastructure consistent. You can track every change using Git. It reduces manual mistakes. You can recreate the same setup anytime. IaC basically brings software-like discipline into infrastructure management. What is Terraform? cloud-agnostic -> works with AWS, Azure, GCP, Kubernetes, Cloudflare and more. Declarative -> You describe what you want, and Terraform builds it. Easy to version control -> because everything is written in files. Powered by providers -> AWS, Azure, GCP etc. each have their own provider plugin. One thing that stood out to me was Terraform's state file. Terraform stores the details of all created resources inside a file called terraform.tfstate. This helps Terraform understand what already exists and what changes need to be made. Terraform Workflow: Write -> Create .tf file. Init -> Downloads provider plugins. Plan -> Shows what Terraform will create or modify. Apply -> Makes the actual changes in your cloud account. Destroy -> Declares everything when you're done. This workflow makes Terraform predictable and safe.  ( 6 min )

In 2010, the web was simple. PHP, Rails, or a bit of jQuery on top of some Twig templates. The server rendered the page, you clicked a link, the browser fetched a new one. That was it. It was predictable. Honest. And slow. Then we saw the future — and it was running in the browser. What if the client handled everything? No refreshes, no full reloads, just pure JavaScript bliss. We sprinted into that future with React, Redux, Angular, and a thousand frameworks that promised to make the web feel alive. And then, somewhere along the way, we started missing the simplicity we left behind. Server templates were simple — and static.

View the webpage on different devices' screen dimensions. Basically, it's the Swiss Army Knife that makes our lives easier. ## BUT!! How about doing the same stuff on the mobile devices? What if there's a bug that's showing up in only the mobile devices? Well, I personally have run into such cases several times and there's honestly no mobile App that's going to save our bum or at least make things easy. Well good news for us because I've found an approach that honestly blew my mind! ## The Solution I'm using my Android Smartphone as I write this article. And we'll be using Chrome browser. This approach has a tiny prerequisite: You need to have developer options enabled on your smartphone before you proceed. Both your PC and your smartphone should be under the same network. We'll be using the Chrome Browser for this article. This means that you'll be needing Chrome both your PC and your smartphone. That's it! Now let's go step by step, shall we? Connect your smartphone with your computer with a USB cable. Open Chrome browser on your PC and type the following URL on the URL bar: chrome://inspect/#devices Now, once you connect your phone with your PC, you'll see the following message on your notification tray. Click on it. Search for Wireless Debugging. Then allow it. Now open your chrome browser from your phone and open any website. Then look at your PC's chrome browser and you'll find all the tabs opened on your phone. Like so. inspect. And if you have come this far, thank you so much! Please let me know if I missed anything!

Building a marketplace sounds straightforward until you're knee-deep in edge cases nobody warned you about. After watching countless marketplace projects stumble over the same hidden obstacles, I've compiled this list of critical issues that are being overlooked consistently. Your product team says: "Just show available inventory in real-time." But in reality, a seller lists their handmade jewelry on your platform, Etsy, Instagram, and their own website. By the time your customer clicks "buy," it's already sold elsewhere. Now you're processing refunds and apologizing while your trust score plummets. Most teams discover this after launch when angry customers start leaving reviews about "fake inventory." The real problem? You can't control what happens outside your platform.

When testing consumes considerable amount of your development cycle, AI changes everything. But most organizations are optimizing for the wrong goal. I have guided engineering organizations through every major technology evolution over the past two decades, including the migration from manual QA to automated suites, waterfall phases to continuous testing in DevOps pipelines. The AI transformation is different. It requires reconceiving what testing means and who does it. Traditional testing treated quality as verification. Write code, write tests (or vice versa when using TDD), run tests, fix bugs. AI makes that sequence obsolete. When AI generates comprehensive test suites in hours, analyzes production telemetry to identify untested paths, and predicts failures before they happen, the bott…  ( 14 min )

Web fonts are one of the easiest places to lose performance—and one of the easiest to fix. Most sites ship multiple formats, oversized files, or unnecessary weights. Here's a compact guide to optimizing your fonts the right way. woff2 is the smallest, fastest, and most compressed format. eot svg ttf A clean modern declaration looks like: @font-face { font-family: 'Poppins'; src: url('Poppins.woff2') format('woff2'); font-weight: 400; font-style: normal; font-display: swap; } If you still support older environments, fallbacks are fine—but keep them minimal: @font-face { font-family: 'Poppins'; src: url('Poppins.woff2') format('woff2'), url('Poppins.woff') format('woff'); font-weight: 400; font-display: swap; } Many projects include full font families (100–900) when they only use 400 and 600. Audit your CSS → keep only what you need. font-display: swap It eliminates invisible text (FOIT) and improves perceived performance. font-display: swap; This ensures text renders immediately using a fallback font, then swaps when the custom font loads. Most font files include far more glyphs than you need: Cyrillic Arabic Vietnamese Symbols Full Unicode ranges If your site uses only Latin characters, subsetting can reduce file sizes by up to 70–90%. Two great tools: https://transfonter.org/ (Upload → subset → download optimized woff2) https://gwfh.mranftl.com/fonts (Self-host Google Fonts + get correctly pre-built subsets) For your main UI font, consider preloading: Use woff2 (and fallback to woff) Remove eot, svg, and ttf unless required Keep only the weights you use Always include font-display: swap Subset using Transfonter or Google Webfonts Helper Preload critical fonts Small changes → big wins.

If you’re also making the same transition You’re not alone Let’s build better things together  ( 6 min )

A simple, practical guide to how different API styles actually work - and when to use which. Every backend uses APIs; but APIs themselves come in many shapes. After writing two chapters on: how APIs behave how they grow in complexity …the final missing piece is understanding how different API styles work, and how they shape your architecture, your frontend, and even your debugging workflow. This chapter aims to be that map; clean, visual, and beginner-safe. 1. REST, GraphQL, RPC, Serverless & Webhooks - The Simple Definitions Let’s start with one-sentence clarity. REST (Representational State Transfer) A URL represents a resource, and HTTP verbs represent actions. Analogy: Ordering from a fixed menu. GraphQL Ask the server exactly for the data you want.

The repository pattern is an essential part of object-oriented software development. It has become the most popular abstraction to retrieve data from the database and map them into business objects (Aggregates). Lately I have noticed that many developers choose to restrict their repository to follow a CRUD (Create, Read, Update, and Delete) pattern, where the methods' names are generic and contain a verb associated with CRUD such as get or delete. The methods are stay highly versatile by accepting a object parameter with many properties so the consumer ca re-use the method in many different scenarios. Example of a User repository interface (typescript): export interface IUserRepository { getUser({ id?: number, email?: string, role?: string }): Promise } This pattern seem to be lo…  ( 7 min )

Best Picture Power Rankings & the Super-Sincerity of ‘Sentimental Value’ Sean Fennessey and Amanda Dobbins kick things off by breaking down Warner Bros. Discovery’s looming sale—will Paramount, Comcast or Netflix swoop in?—before tearing into the baffling new Colleen Hoover flick Regretting You (starring Allison Williams and Dave Franco), which left them scratching their heads. Next up, they dive deep on Joachim Trier’s Sentimental Value, pondering why its earnest vibes click for some viewers and totally miss the mark for others. The episode wraps with Trier himself calling in to reveal how much of his own life shaped Stellan Skarsgård’s character, why being a good listener makes for great storytelling, and what it was like shooting in his childhood neighborhood.

How I transformed notification logging from a blocking operation to a non-blocking batch system, handling 100,000+ logs efficiently? After refactoring my Firebase notification service into a queue-based architecture (Part 1) and breaking down the monolith into clean utilities (Part 2), I hit another bottleneck: logging. Saving push notification results to the database was blocking my notification sending pipeline, adding 30-50% overhead to every batch operation. Here's how I transformed the logging system from a synchronous bottleneck into an efficient asynchronous batch processor that handles 100,000+ logs without breaking a sweat. In the refactored queue-based system, the flow looked like this: Query DB → Filter Users → Send Notifications → ❌ WAIT for logs to save → Next chunk …  ( 18 min )

In a recent sprint, one of my junior developers asked me how *LaunchDarkly * actually fits into our React-Native-Web codebase. Not just the syntax — but the system around it. It turned into one of my best mentoring sessions this year. We discussed the fundamentals: LaunchDarkly’s purpose in multi-platform environments Why feature flags matter more than config toggles How variations allow safe experimentation How rules can target specific user segments Why controlled rollouts reduce production anxiety And how our RN-Web setup consumes flags in a unified pattern What surprised me wasn’t the complexity — it was how powerful these concepts become once a developer truly understands them. Teaching this reminded me of a simple truth: And sometimes, the biggest impact you make isn’t shipping a feature… It’s helping someone else ship one, safely.  ( 6 min )

TL;DR Embedding a wallet SDK is no longer just about generating keys and sending transactions. In 2025, it’s about onboarding flows, session keys, smart accounts, gas abstraction, and a UX that feels like any modern app. This guide walks through best practices used by production teams, patterns we’ve seen building Openfort’s embedded wallet SDK, and the architectural mistakes to avoid. 1. What “Embedding a Wallet SDK” Actually Means Most people think “wallet SDK” = signing transactions. In reality, embedding a wallet SDK means your app: creates a wallet inside your app’s UI manages authentication → (email, passkey, OAuth, device) handles key sessions creates + manages smart accounts (EOA → SCW) abstracts gas or sponsors transactions orchestrates signatures securely on web, mobile, or …  ( 9 min )

If you dive into the specification of package.json you might be surprised to learn that next to the options dependencies and devDependencies there are also the options bundleDependencies, optionalDependencies and peerDependencies. Recently we have been migrating our main application to an architecture with multiple frontends based on NextJS. Since we have shared components and logic we expose these as packages with peer dependencies. And I found that a good number of my colleagues are unfamiliar with peer dependencies. In order to explain peer dependencies, it is beneficial to first look at how NPM and PNPM work. Whenever you install a dependency in your project, this dependency can have other dependencies (these are typically referred to as non-root dependencies or transitive dependencies…  ( 13 min )

Inheritance vs Composition: The Principle of Independent Variation Explains Why "Favor composition over inheritance" is one of the most cited design guidelines in software engineering. But have you ever wondered why this works—and more importantly, when inheritance is actually appropriate?

If you search online for how to draw a triangular shape in CSS, chances are the top results will still recommend the border method, as described in this 15-plus-year-old CSS-Tricks article: The idea is a box with zero width and height. The actual width and height of the arrow is determined by the width of the border. In an up arrow, for example, the bottom border is colored while the left and right are transparent, which forms the triangle. .arrow-up { width: 0; height: 0; border-left: 5px solid transparent; border-right: 5px solid transparent; border-bottom: 5px solid black; } I still stand by most of what I wrote in my original article: this method is a hacky solution from a time when there were no other CSS options.

Introduction The reason I ended up writing this post started from pure coincidence. While browsing through technical blogs(sorry its korean ref), I saw an article that made me think about path auto-completion. When I first read the post, I genuinely thought it was impressive. But there were parts I couldn’t immediately wrap my head around, and I kept wondering whether there was room for improvement. In the projects I had worked on before, I didn’t even have path auto-completion— Because of that, whenever a route changed, I had to update every single reference. So I decided that I needed path auto-completion and type safety of my own. But I wasn’t satisfied with applying the blog’s solution as it was. Not to criticize it, but I didn’t like the idea of redefining every route inside a singl…  ( 9 min )

A guide to understanding Python Poetry, how it works, and how to use it in your next Python project. Python development looks simple from the outside. But managing real projects is rarely easy. You need to install packages, update them, avoid version conflicts, create virtual environments, and prepare your project for distribution. Many beginners think they can handle everything with pip and venv. This works for small scripts, but becomes messy once your project grows. Poetry solves this problem by giving you one clean workflow for managing Python projects from start to finish. Poetry brings structure to your project. It automates package management, creates virtual environments independently, and prepares your project for building and publishing. It replaces many scattered tools, bringing…  ( 12 min )

AI Amnesia: Selectively Forgetting with Geometric Unlearning Imagine an AI trained on customer data that needs to 'forget' information related to a specific individual for legal reasons. Or, consider a model plagued by bias from a tainted dataset, where we need to surgically remove the problematic influences without destroying the model entirely. Can we make AI selectively forget, without harming its overall performance? At its core, geometric unlearning is about carving out a precise 'forgetting pathway' in the model's learning space. It's like carefully removing a single brick from a building's foundation without causing a collapse. The key idea is to decompose the 'forget' update into two components: one that is orthogonal to the knowledge we want to keep and another that is tangenti…  ( 7 min )

As developers (and especially as students), we often fall into the trap of signing up for a dozen "free tier" SaaS products. Notion for notes. Jira for tasks. Vercel for hosting. Slack for chat. It works great... until you hit a paywall, or they change their pricing, or you realize you don't actually own any of your data. I decided to fix this. Over the last few weeks, I curated a massive list of Open Source alternatives to the most popular SaaS tools. These are tools you can self-host, run locally, or use for free without giving away your privacy. I call it The Free Stack. Here are 5 of my favorite discoveries from the list: If you love Notion but hate that it's cloud-only, check out AppFlowy. It's built with Rust and Flutter, meaning it's blazingly fast. You have 100% control over your data. This is a game changer. Coolify is an all-in-one PaaS that helps you self-host your own applications, databases, and services. It connects to your GitHub and deploys automatically. Designers, rejoice. Penpot is the first open-source design and prototyping platform meant for cross-domain teams. It is SVG-based and works right in the browser. You probably know this one, but it deserves the hype. Supabase gives you a Postgres database, Authentication, instant APIs, and Realtime subscriptions. Stop paying huge monthly fees just to have a conversational form on your site. Typebot is a visual conversational form builder that you can host yourself. I have compiled 50+ tools covering: 🏰 Project Management 💬 Communication 🛠️ Dev Tools 📊 Analytics 🔒 Privacy You can find the full list on GitHub here: The Free Stack on GitHub If you found this useful, dropping a Star ⭐ on the repo really helps others find these tools!

In MongoDB, a write concern of w:1 indicates that a write operation is considered successful once the primary node acknowledges it, without waiting for the data to be replicated to secondary nodes. While this reduces latency, it also introduces the risk that if the primary fails before replication occurs, the written data could be lost. In replica sets with multiple voters, such writes can be rolled back if a failure happens before a majority acknowledges the change. This is not the default setting. Most clusters (Primary-Secondary-Secondary) use an implicit w:majority write concern, which ensures durability in the event of a zone failure. The implicit default write concern is w:1 only when an arbiter is present (Primary-Secondary-Arbiter) or when the topology lowers the number of data-bea…  ( 13 min )

AI Auto translation tools. In a global market where every single message matters, even the tiniest mistake in ChatGPT translation can cost the business trust, revenue and loss of brand credibility. Nowadays, companies translate the content faster than ever, however, accuracy has not caught up with the speed. And it is exactly this gap where problems start. For many years, companies used to depend on basic auto-translation tools to promote global communication. These tools were said to provide the advantages of speed, affordability and convenience but their hidden risks were never mentioned. The main issue is that of accuracy. The basic tools do word-by-word translation rather than capturing the deeper meaning. Thus, it leads to errors in tone, cultural mismatches and expressions that misle…  ( 11 min )

I’m building DocBeacon - secure document sharing and tracking platform. It shows exactly how readers interact with each page: scroll depth, dwell time, replays, and even heatmaps of attention. Recently I’ve been thinking about going a step further. Instead of just showing behavior metrics, what if DocBeacon could estimate how emotionally or cognitively engaged a reader is with a document? Something like a persuasion score that reflects how much a sales proposal actually moved them — did they seem convinced, neutral, or totally uninterested? The basic idea sounds simple: use past reading behavior data and train a model to predict the likelihood of acceptance. But here’s the problem: I have plenty of behavioral data (how people read), yet no solid labels on what happened after they read. Without knowing whether the reader ended up accepting the proposal, replying, or ghosting, the model can’t really learn meaningful correlations. Has anyone here tackled a similar cold-start problem? Curious to hear how others would approach building a persuasion predictor when you only have half the story.  ( 8 min )

Intro Here is this week's update on my plugin suite for Unreal Engine development in Neovim. My stance hasn't changed: "For heavy-duty debugging, full IDEs like Visual Studio or Rider are still king." So, this week, I released a debugging plugin to grant that wish, along with a specialized file explorer dedicated to the Unreal Engine project structure. UDB.nvim: A zero-config debugger bridge (no launch.json needed!). UNX.nvim: A lightweight logical file viewer & symbol tree specialized for UE projects. With these additions, I feel like Neovim has finally become a true "IDE for Unreal Engine." UDB.nvim is, as the name suggests, a bridge connecting Neovim (nvim-dap) and the Unreal Engine debugging environment. Its biggest feature is "Almost Zero-Config." launch.json. UDB automates this b…  ( 8 min )

Some companies seem to keep moving forward while others struggle to keep pace. The difference often lies in digital transformation consulting, not in buying the latest software, but in rethinking how a business operates at every level. It’s about modernizing outdated systems, improving workflows, and helping teams work faster, smarter, and more efficiently. Consultants play a crucial role in this process, guiding organizations through strategy, technology adoption, and cultural change. They help businesses bridge the gap between where they are and where they need to be, ensuring progress that’s both measurable and sustainable. This article explores what digital transformation consulting really means, how it works in practice, and what to look for when your business is ready to evolve. Wha…  ( 11 min )

The math that changed how I think about AI features A client messaged me about adding ChatGPT to their invoicing app: "Can we add AI to help users write invoice descriptions? Budget is $15K." They have 500 users paying $20/month. Seemed straightforward. I started prototyping. The code was simple: const response = await openai.chat.completions.create({ model: "gpt-4", messages: [{ role: "user", content: userPrompt }] }); But before quoting, I decided to calculate the real long-term costs. What I found surprised me. I spent two weeks diving into AI economics. Not because I'm some expert, but because I couldn't find clear information anywhere about what it actually costs to run AI features at scale. Quick note: I built a simple calculator while researching this. If you want to run your o…  ( 9 min )

2024 was the year of pilot projects. Pharma companies experimented with GenAI, tested narrow use cases, and debated its potential. In 2025, the conversation has shifted. Leaders are no longer asking if GenAI belongs in life sciences. The question now is where and how. That shift matters. GenAI is not just a shiny new tool. Done right, it can transform how pharmaceutical companies accelerate R&D, manage compliance-heavy processes, and improve the daily lives of both field teams and patients. But done wrong, it risks creating inefficiencies, compliance headaches, or worse, regulatory pushback. At Newpage, we see two patterns emerge when working with pharma and biotech teams. First, there are a handful of use cases that are mature, safe, and ready to deliver ROI right now. Second, there are o…  ( 7 min )

Every life sciences leader agrees on one thing: Salesforce should be a game-changer for pharma. On paper, it offers a complete view of HCPs, faster patient engagement, compliant workflows, and insights that help commercial and medical teams move smarter. But here is the paradox. Despite all that potential, a large percentage of Salesforce implementations in pharma fall flat. Some never take off, others become expensive shelfware, and a few even create compliance risks that no one anticipated. So what is really going on? As explored in detail at Newpage, it is rarely the platform itself that causes failure. The real challenge lies at the intersection of three forces: technology, regulation, and real-world pharma workflows. If those are not aligned from the start, even the best Salesforce bu…  ( 7 min )

Better Agents CLI with Kilo Code and LangWatch This is a guest post by Rogerio Chaves, CTO and Founder of LangWatch. He brings 14 years of software engineering experience to solving one of AI's biggest challenges: making AI agents more reliable, testable, and production-ready. Today, more than 95% of enterprise agent projects fail to reach production due to a lack of reliability, evaluation discipline, and trust. Most are abandoned entirely, never making it past prototype phase. The industry needs to mature. We need to build Better Agents. Over the past two years, LangWatch has worked with leading companies to help them cross the barrier of agent reliability and bring agent systems safely into production, while Kilo Code has been the leading open source coding assistant helping teams to…  ( 7 min )

Today, we talk about a bug that shows in practice how "code sausage" can cause a series of problems related to the last line effect and careless copy-paste, as well as lead to new errors. The PVS-Studio team not only creates new diagnostic rules, but also gradually refines the existing ones. For example, we've recently enhanced one of the oldest diagnostic rules in the C# analyzer, V3001, to make it detect redundant parentheses more accurately. As a result, the analyzer started detecting new bugs, one of which we show you. This case was detected in the Space Engineers project; this is one of the projects in our internal regression testing database. We use a specific old project version to compare how the analyzer behaves on the same code across updates. But if we look at the latest source…  ( 8 min )

As developers, we're wired to build and ship. We launch a feature, merge the PR, and move on to the next ticket. But in the world of B2B SaaS, the real work begins after the customer signs up.

The Beatles' "Now And Then" won a Grammy in 2024, but John Lennon had been dead for over four decades when he sang the lead vocals. Using machine learning to isolate Lennon's voice from a decades-old demo cassette, the surviving band members completed what Paul McCartney called "the last Beatles song." The track's critical acclaim and commercial success marked a watershed moment: artificial intelligence had not merely assisted in creating art—it had helped resurrect the dead to do it. As AI tools become embedded in everything from Photoshop to music production software, we're witnessing the most fundamental shift in creative practice since the invention of the printing press. The traditional image of the artist—solitary genius wrestling with blank canvas or empty page—is rapidly becoming a…  ( 23 min )

I’m excited to announce Rubree, a modern regular expression editor for Ruby developers — inspired by Rubular but rebuilt from scratch using Ruby, Rails, and WebAssembly (Wasm). Rubular has long been a beloved tool for Rubyists, but it comes with some limitations: Runs on older Ruby 2.5.9, which affects speed and maintainability Not open-source, making customization and internal investigation difficult Matching is server-dependent, requiring backend processing for every input Cannot visualize regex structure as a railroad diagram (like Regexper) Replacement preview is unavailable Rubree addresses these challenges by redesigning both the UI and backend logic, running entirely in the browser for a fast, modern regex experience.

I was digging around some of my old blogs recently and spotted something interesting, well not interesting, but unexplained. I blog about the Power Platform, a lot, and one of the things I don't blog about is crypto, so I was surprised to see that a few on my blogs had these tags: #crypto #cryptocurrency #bitcoin #offers #web3 Yep it looks like someone hacked my tags, most likely in conjunction with spam comments to push something dodgy. I wanted a quick way to check all of my blogs and fix any, and luckily there is a API for that. As Dev.to is built on Forem it has a robust and open api (No known rate limits and auth only for personal permissions like creating a blog).

A Data-Driven Approach to Predicting Winners in the Wildest Market on Solana The Solana memecoin ecosystem moves faster than almost any market in crypto. Tokens appear, pump, rug, and disappear in minutes. When I started reviewing and improving the Solana Memecoin Intelligence System, I expected a simple prediction model. Instead, I discovered a deeply engineered ecosystem combining machine learning, blockchain intelligence, real-time market data, and a live Telegram alerting system. This project taught me far more than ML.

The first time I ran the same code review prompt through GPT-4.1, Claude Sonnet 4.5, and Gemini 2.5 Pro simultaneously, I discovered something uncomfortable: I'd been trusting the wrong model for the wrong tasks. GPT-4.1 gave me creative refactoring suggestions but missed a critical edge case. Claude caught the edge case immediately and explained the type safety issue in detail. Gemini flagged a performance bottleneck I hadn't even considered. Each model saw something the others missed. For two years, I'd been using ChatGPT exclusively because it was the first AI I'd adopted. I assumed if one AI could help with code, it was good enough. But watching three different models analyze the same problem revealed a truth most developers don't realize: no single AI model is best at everything, and …  ( 11 min )

Google's had a comfortable run as the gatekeeper of internet traffic. Twenty-five years of SEO professionals optimizing for one algorithm, one set of rules, one way of thinking about search. Then ChatGPT Search launched. Now we're not just optimizing for crawlers and ranking factors. We're optimizing for AI that reads, understands, and synthesizes content before deciding whether to cite it. The rules haven't just changed—the entire playing field shifted. And here's the thing: most of the SEO advice you'll find is still stuck in 2019. "Just create quality content" they say, as if that phrase has ever meant anything specific.

Over the last few weeks I've been building an 8-register VM in Rust for a small Lisp-like DSL, plus a proof pipeline that turns programs into STARK proofs of execution. The DSL is compiled by the zk-lisp-compiler crate into a compact Op sequence, and proofs are generated through a dedicated backend built on top of the winterfell crate. A few details that might be interesting from a Rust/efficiency point of view: I defined a unified execution trace (VM registers, RAM tables, Merkle gadget, Poseidon2 lanes, ROM accumulator) in a single Columns layout. The VmTraceBuilder simulates the Op sequence, seeds registers, and fills a Winterfell TraceTable while keeping allocations predictable (pre-zeroed trace, cached Poseidon2 params, partition selection).

Razor Pages vs MVC: Quando escolher e por quê Uma análise prática e arquitetural para quem constrói aplicações .NET modernas no mundo real. Ao iniciar um novo projeto web em .NET, uma das primeiras decisões é escolher entre ASP.NET Core MVC e ASP.NET Core Razor Pages. Embora ambos coexistam dentro do mesmo framework, eles representam modelos mentais diferentes — e essa escolha impacta clareza, manutenção, ritmo de entrega e arquitetura. Neste artigo, vamos explorar quando Razor Pages é superior ao MVC, quando o contrário é verdadeiro, e — principalmente — como arquitetos e desenvolvedores podem decidir de forma prática e segura. A diferença entre Razor Pages e MVC não é técnica — é conceitual. Controllers + Actions Fluxo centralizado Flexível para APIs e rotas complexas Ótimo para aplicações grandes e arquitetadas PageModel por página Fluxo distribuído Ideal para CRUDs e sistemas de gestão Arquitetura limpa e previsível Em resumo: MVC organiza por tipo. Razor Pages organiza por funcionalidade. Cada página possui seu próprio PageModel, facilitando leitura e manutenção. Menos arquivos, menos roteamento manual, mais foco em regras e serviços. ERP, CRM, backoffice, intranets — todos combinam melhor com páginas orientadas a funcionalidade. Domínio → Serviço → Repositório → PageModel → UI. Fluxos avançados, lógica rica de controle. React/Angular pedem APIs independentes. MVC oferece mais controle. Quando seu design exige isso. Tipo de Projeto Melhor Opção CRUD corporativo Razor Pages Ferramenta administrativa Razor Pages Portal interno Razor Pages Aplicação SaaS baseada em formulários Razor Pages API + SPA MVC ou Minimal APIs Rotas complexas MVC Para a maioria dos sistemas reais: Comece com Razor Pages. Só evolua para MVC se realmente houver necessidade. Razor Pages simplifica, organiza e acelera entregas — especialmente quando combinado com serviços, repositórios, validações e um bom guideline arquitetural. 👉 Criando uma ASP.NET Core WebApp Razor Pages do zero (em 5 minutos).  ( 7 min )

What is Fork Fork is a git client that runs your git commands for you inside of an interface. Similar to other products like GitHub Desktop abd GitKraken. For provides a great deal of flexibility when setting up custom commands. The interface is decent and provides quick and easy GUI for all your Git needs. However, being able to setup your client to run various commands on the repo is very handy. Currently I have my JetBrain's products plus the ability to scan for secrets using nosey parker. All very very handy. I even use AICommit2 from time to time with a click of a button. Using fork to delete a file out of git history. 1.) Create a Custom Command 2.) Call the custom command 'Remove Selected File from History' Target needs to be File visible in file context menu 3.)

Data analysts spend more time cleaning data than analyzing it. In fact, in most real-world projects, 60–80% of your time goes into preparing data for meaningful insights. Here are the five most common data quality problems and practical steps to solve each one. 1. Missing or Null Values Missing data can distort metrics, create gaps in reports, or lead to inaccurate ML models. Causes: How to fix it: Identify missingness patterns using COUNT(*) in SQL or df.isna().sum() in Python. Drop rows only when missing data is irrelevant. Impute using averages, medians, or domain logic. Use Power Query’s “Replace Errors” or “Fill Down” functions for structured fixes. 2. Inconsistent Formatting You’ve probably seen this: “Kenya”, “kenya”, “K E N Y A”, or mismatched date formats in the same column. Why it happens: How to fix it: Apply standard casing (upper/lower/title). Convert all dates to a unified ISO format (YYYY-MM-DD). Use Excel Power Query’s “Transform → Format” options. In SQL, standardize with functions like UPPER(), TRIM(), or TO_DATE(). 3. Duplicate Records Why it happens: How to fix it: Identify duplicates using ROW_NUMBER() windows in SQL. Use Power Query’s “Remove Duplicates”. Implement unique IDs early in the pipeline. In Python, use df.drop_duplicates(). 4. Outliers and Incorrect Values Some values are valid extreme cases; others are simply errors (like a customer aged 600). Why it happens: How to fix it: Visualize distributions using box plots or histograms. Apply domain thresholds or rule-based logic. Use interquartile ranges or z-scores for statistical outlier detection. Create automated validations in Power BI or SQL. 5. Mixed Granularity Data at different levels combined into one column or table — e.g., weekly and monthly data in the same dataset. Why it happens: How to fix it: Split datasets by granularity before analysis. Create dimensional tables for dates, products, etc. Aggregate or disaggregate consistently before joining. Use a proper star schema when possible.  ( 7 min )

When working with Git, developers often need to understand how much their current branch differs from the main branch. This can help in assessing the scope of changes, planning reviews, or making decisions before merging. One useful metric is the total number of lines added and removed between branches. Counting the lines of code changed gives a quick snapshot of the volume of work done. It helps to: Gauge the size of your feature or fix. Estimate code review effort. Track progress against expectations. Identify large or complex changes that might require extra testing. The Git command line provides simple ways to check these differences precisely. The most straightforward command is: git diff --shortstat main...HEAD Here’s how it works: git diff shows changes between commits or branches. main...HEAD compares your current branch (HEAD) with the main branch. --shortstat gives a brief summary report with the total files changed, and lines added and deleted. For example, running this command might show: 3 files changed, 45 insertions(+), 20 deletions(-) This means across 3 files, you've added 45 lines and removed 20 lines compared to main. If you want to see the exact line changes per file, you can use: git diff main...HEAD --numstat This command outputs a list where each line contains the number of added and deleted lines per file. It’s handy for deeper inspection or for scripting purposes.  ( 7 min )

The Great Logic Revolution: Why I Killed && and || in My Programming Language For decades, programmers have struggled with boolean operator confusion. How many times have you seen: if (user.isActive && user.hasPermission || user.isAdmin) { // Wait, does this mean (A && B) || C or A && (B || C)? } I decided enough was enough. In Coderive v0.2.3, I completely removed && and || operators. Here's why and what replaced them. The Problem with Traditional Boolean Operators · Precedence confusion: && vs || precedence trips up beginners and experts alike The Solution: Quantifier-First Logic Coderive introduces any[] and all[] quantifiers: # Instead of: if (name != "" && age >= 0 && age = 0, age = 60] # "All scores must be 60 or above" any[users.isActive] # "At least one user must be active" 🐛 Fewer Bugs No more operator precedence debates. The syntax forces clarity. 📚 Beginner Friendly Reads like natural language, lowering the learning curve. ⚡ Built-in Short Circuiting if all[expensiveOperation(), shouldSkip] { # expensiveOperation() won't run if shouldSkip is false } Built Against All Odds What makes Coderive unique is its development story: · Built entirely on a phone using Java NIDE, QuickEdit, and Termux Technical Architecture Coderive isn't just syntax sugar - it's a full compiler: · Dual parser system: ANTLR + manual recursive backtracking Try It Yourself # Run interpreter java -jar coderive.jar program.cod # Compile to native java -jar coderive.jar --native program.cod Join the Discussion I'm convinced quantifier-first logic is the future, but I want to hear from you: · Would you use a language without && and ||?

1. Introduction: The Engine Room of Automation n8n is a robust, open-source workflow automation tool and low-code platform. While standard nodes (Set, If, Merge, Switch) handle linear task execution, the Python Code Node represents the "engine room" of sophisticated automation. It allows users to implement custom logic, complex data manipulations, and performance optimizations that standard nodes cannot achieve. The Code Node and Inline Expressions empower users to perform operations—specifically in data science, string manipulation, and mathematical calculation—that are often more verbose or difficult in JavaScript. A single Python node can effectively replace chains of 10 to 15 standard nodes, resulting in cleaner, more maintainable, and significantly faster workflows. Why Use Python i…  ( 16 min )

Cursor enforces a few core habits to keep edits safe, traceable, and user-friendly. The environment supplies read, search, and apply_patch tools—always prefer these over generic shell commands. Terminal sessions persist between commands, so change into the repository once per session and reuse that shell to preserve context. Because other contributors or automated processes may have touched files, never revert or overwrite changes you didn’t create; instead, work around them unless the user explicitly asks otherwise. Cursor forbids destructive history rewrites such as git reset --hard or force-checkouts unless specifically requested, and it discourages amending commits unless told to do so. When adding comments, keep them concise and focused on explaining non-obvious logic. Default t…  ( 7 min )

I recently published a simple pseudocode runner/editor, and the interesting part is that I built it without any real coding background. The project relies almost entirely on the tools provided by Compyle, including their custom lexer and parser. My contribution was mainly setting up the environment, hosting the project, and making the interface usable. Why I Created This Students preparing for IGCSE and A-Levels often need a quick way to test pseudocode. Most existing tools are either outdated or limited, so having something modern, clean and accessible felt useful. How It Works The heavy lifting in this project wasn’t done by me. Compyle’s internal system handles the important logic: A custom lexer to tokenize pseudocode A custom parser that interprets the structure CodeMirror for the editor interface A clean UI already integrated into their setup Since all the complex parts were already built, I focused on integrating everything, hosting the project, and ensuring the platform feels smooth to use. What I Actually Did Set up hosting Connected the existing components Tweaked the UI where needed Tested the runner for basic I/O behavior I didn’t build CodeMirror, and I didn’t write the lexer or parser. Compyle’s tools handled all of that. My main role was putting the pieces together and making the runner publicly accessible. Why I’m Sharing This A lot of beginners think they need years of experience before they can launch something. This project shows that with the right tools, you can build something functional even if you’re just getting started. If you want to try the pseudocode runner, here’s the project link: Https://pseudorun.tech  ( 7 min )

Consider that your backup is running smoothly. Your dashboards are green. The DevOps team is sleeping peacefully. And yet, behind the calm surface, something is happening. Your API limits are being chewed up, call by call, until you’re throttled into silence. Suddenly, your system stalls – quietly and invisibly. The irony is, you build a backup system for resilience. Now, it’s the vulnerability. There’s a quiet assumption built into most backup systems. It’ll resolve itself if you just throw enough bandwidth, retries, and threads at the problem. However, in DevOps, it’s naive. Dangerous. Why is it dangerous? When every DevOps tool communicates through rate-limited APIs, such as GitHub, GitLab, Bitbucket, or Azure DevOps, there is no alternative. SaaS vendors aren’t being punitive when the…  ( 10 min )

We don’t want to use Spring because, at the moment, we are trying to learn Hibernate, which is a framework itself. So we just want to focus on one framework at this point, and that is Hibernate. First, we create the most basic Maven project Adding hibernate-core dependency org.hibernate.orm hibernate-core 7.1.8.Final We also need to connect to the database, for that we need a vendor, and in this case we are using MySQL.

In today’s fast-moving digital world, businesses need flexible, scalable, and cost-effective infrastructure to keep up with rapid innovation. That’s exactly where Infrastructure as a Service (IaaS) makes a powerful difference. Instead of investing in physical servers, storage, and networking hardware, organizations can access these resources on-demand through the cloud—paying only for what they use and scaling seamlessly as their needs evolve. What Makes IaaS So Essential Today? Every digital service—from mobile apps to enterprise software—needs reliable infrastructure. Traditional on-premise setups are expensive, slow to scale, and demand regular maintenance. IaaS eliminates those challenges by offering cloud-hosted infrastructure that can be provisioned in minutes rather than weeks. Whet…  ( 7 min )

Fast forward to December 2024: Anna and her co-founder Art Abal just launched Vana—a blockchain that lets people own and monetize their personal data—and it's valued at over $1 billion before even trading publicly. But here's the twist that makes this story absolutely wild: Anna's bedroom wall didn't have posters of pop stars or athletes. She had a picture of Janet Yellen, the U.S. Treasury Secretary. This is the story of two Filipino entrepreneurs who met at MIT, worked on data labeling projects in Philippine slums, and decided to build a blockchain that could fight back against Big Tech's data monopoly. And spoiler alert: they just became the 62nd project on Binance Launchpool, with their mainnet launching on December 16, 2024. Let's dive in.

Cross-Modal Knowledge Distillation for smart agriculture microgrid orchestration under multi-jurisdictional compliance It all started when I was experimenting with multi-modal AI systems for environmental monitoring. I had been working on a project that combined satellite imagery, IoT sensor data, and weather patterns to predict crop yields. During my investigation of knowledge transfer between different AI modalities, I stumbled upon something fascinating: the same techniques I was using to transfer learning between vision and sensor models could revolutionize how we manage agricultural microgrids across regulatory boundaries. While exploring cross-modal distillation techniques, I discovered that the challenge wasn't just about transferring knowledge between different data types, but ab…  ( 12 min )

Next month we’re launching a platform we’ve been quietly building for a while — but before talking about the product itself, I wanted to share the real story behind why we built it. Over the past month, more than 200 developers and founders joined our Beta list. Most of our time since then has been spent in calls, DMs, and long user interviews trying to understand a simple question: “Why does it still take so long to turn an idea into a working product — even with all the AI tools available today?” What we found was surprisingly consistent across teams, solo devs, and early-stage founders. 📝 1. Requirements Are Still the Silent Bottleneck Most people assume coding is the slow part. I don’t know if my requirements are complete until something breaks. We start building and realize half the …  ( 8 min )

In a rapidly evolving digital landscape, businesses can no longer afford to depend on aging, inflexible, or hard-to-maintain applications. Application modernisation has become the strategic pathway for companies looking to stay competitive, enhance performance, and meet rising customer expectations. Instead of discarding legacy systems entirely, modernisation focuses on transforming them—making your applications faster, scalable, and more aligned with today’s cloud-driven world. Why Application Modernisation Matters Today Legacy applications often come with technical debt, outdated architectures, and high maintenance costs. They might still house valuable business logic, but they limit innovation and slow down digital transformation efforts. As customer demands grow and technology advances…  ( 7 min )

AI Agents have evolved a lot from when I started using them in 2022 till now. If you pay close attention, you will notice that these agents are growing not just in capabilities, that is, the kind of task they can do, but in understanding, which in my opinion is far important than the type of tasks they do. I say this for two reasons: An AI agent is as good as the person using it. An AI agent with a deep understanding of a particular context or subject matter will outperform generalistic AI agents long-term. If you look at this from a wide view, the same applies to humans. A person who has developed knowledge, understanding and expertise in one area, for example, Finance, has built not just skill but discipline over an extended period of time. Say that person wants to learn Product des…  ( 15 min )

The Problem That Inspired This Article Recently, I encountered an interesting situation. I opened a certain web resource (which I won't name) and tried to view a list of data. The page started loading... and loading... and the browser froze. After restarting the page and opening DevTools, the picture became clear: the API endpoint was returning all records in a single request - tens of thousands of rows in a JSON response over 50 MB in size. The browser simply couldn't handle it. Testing the request through Postman confirmed my suspicions: GET /api/items Response: [ { "id": 1, "name": "Item 1" }, { "id": 2, "name": "Item 2" }, ... { "id": 50000, "name": "Item 50000" } ] // 50 MB JSON, response time: 12 seconds This incident prompted me to write an article about how to properly s…  ( 10 min )

Documentation debt is real. Every developer knows the sinking feeling of discovering their API docs are three versions behind the actual implementation. The endpoint that was renamed last sprint? Still documented under the old name. That new required parameter? Nowhere to be found in the docs. The traditional approach to API documentation—manually writing and updating documentation files—creates an unsustainable maintenance burden. But there's a better way: automatic documentation generation from your OpenAPI or Swagger specifications. This isn't about shortcuts or compromising quality. It's about leveraging the specifications you're already maintaining to create documentation that's always accurate, always current, and always trustworthy. The fundamental problem with manual documentation …  ( 14 min )

I. What Is an Automotive MOST Cable? Core Basics Key Definition & Working Principle An automotive MOST cable is the physical transmission medium for the MOST bus system, which transfers digital data (audio, video, navigation maps, and sensor data) between vehicle components at speeds up to 150 Mbps (for MOST 150, the latest standard). Unlike point-to-point wiring, MOST uses a ring topology: all connected devices (e.g., head unit, speakers, rear-seat entertainment) form a closed loop, allowing data to flow in either direction. The cable’s core function is to maintain signal integrity over long distances (up to 20 meters in a vehicle) while resisting electromagnetic interference (EMI) from engine components and other wiring. This is achieved through specialized materials and shielding—critic…  ( 11 min )

One of the new providers that Brighter V10 supports is MongoDB. In this article, I'll explore how to use it with the Inbox and Outbox patterns. MongoDB is a popular NoSQL document database that stores data in flexible, JSON-like documents. Its scalability and performance make it an excellent choice for high-throughput applications, and its document model maps naturally to the message structures often used in distributed systems. We will build a .NET 8+ service that consumes/produces messages from a Kafka topic, processes them using Brighter, and uses a MongoDB database as the persistent inbox and outbox to guarantee that all messages are sent. We also need to configure a distributed lock to avoid publishing duplicate messages when running this application in a multi-node environment. You c…  ( 10 min )

“È bravo, ma non si impegna.” ( “He is very smart, but if he put in more effort, he could achieve so much more.” ) This sentence followed me for my entire childhood. “You could have gotten an A… if only you had worked harder.” Sometimes I even got worse grades than classmates who had identical results because they “worked hard”, so they were rewarded, while my work was discounted and attributed to “talent.” I can’t say whether those comments shaped who I am today, or whether something deeper was already there.

React is a powerful library for building user interfaces, but as applications grow in complexity, developers often run into a few tricky state management issues. Three of the most common are the "zombie child" problem, UI tearing in concurrent mode, and performance degradation from React's Context API. Fortunately, a lightweight and elegant state management library called Zustand provides a simple solution to all three. Let's dive into what these problems are and how Zustand helps you sidestep them entirely. The "zombie child" effect happens when a parent component re-renders, but a child component that has been unmounted (or is in the process of unmounting) still manages to trigger a state update. This child is a "zombie"—it's not really alive in the component tree, but its old logic (oft…  ( 9 min )

I’ve been building a project, and I finally pushed it live: Abliteration : a less‑filtered LLM chat and API. At a high level: It’s a web chat where you can talk to a “less‑filtered” LLM. It’s also an API you can call from your own apps (OpenAI‑style JSON). It’s aimed at developers doing things like: red‑teaming / robustness testing internal tools creative / experimental projects The goal isn’t “no rules, pure chaos”. The goal is: “stop refusing every borderline or research prompt, but still block clearly harmful stuff.” When I started playing with different LLM APIs, I kept running into the same pattern: I’d write a prompt for something perfectly legitimate (e.g. security testing, fiction, simulations). The model would respond with some variation of “I’m sorry, I can’t help with that”. I’d spend more time fighting the guardrails than working on the actual idea.

There's a troubling trend I've been observing in software development, and it keeps me up at night. AI-powered code generation has become incredibly popular, and one of its most promoted use cases is generating unit tests.

Lisp provides metaprogramming via macros, which are essentially code generators embedded in the language. Beyond Lisp, modern languages like Scala and Rust also offer macro designs, but macros are generally seen as complex, low-level technologies and rarely make it into the average programmer’s toolbox. XLang, part of the Nop platform, is one of the core technologies implementing the principles of Revers…  ( 13 min )

The Nop platform offers a language-oriented programming paradigm: when solving problems, we tend to first design a Domain-Specific Language (DSL), and then use that DSL to describe business logic. The Nop platform greatly simplifies the process of creating custom DSLs. The value of a DSL lies in distilling domain-specific logical relationships and defining atomic semantic concepts unique to that domain. The concrete syntax is not the key. After code is parsed by a Lexer and Parser, it yields an Abstract Syntax Tree (AST), and all program semantics are, in principle, carried by the AST. Both XML and JSON are tree structures and can directly represent an AST, thus completely avoiding the need to implement a special Lexer and Parser. Lisp does exactly this by directly using a general S-Expr t…  ( 12 min )

Last week I noticed something annoying: the engagement on my Week 1 and Week 2 posts dropped, even though the content was objectively good. So I asked Perplexity when developers actually read dev.to and the answer was basically: please stop posting on Saturdays. No one is there. From there, Wykra updates move to Monday morning. Let's see if the stats agree. This week is about taking Wykra from we can find influencers to we can filter them and analyze them in depth. In the previous post I explored several ways of discovering influencers and for this week I want to combine a couple of those methods rather than rely on just one. The plan is to mix a targeted Google query through the Bright Data SERP dataset with a Perplexity prompt through OpenRouter (or Bright Data) and see whether using th…  ( 14 min )

Is Big Interview Worth It? An Honest Developer’s Take If you’ve ever sat in front of your laptop, sweating bullets before a coding interview, you’ve probably asked yourself: “Why didn’t I prepare more?” Then you open YouTube, watch a 10-minute video about how to “crush your interviews,” close the tab, and go back to Twitter because panic is exhausting. That’s usually when people start looking at interview prep platforms, and one name that pops up a lot is Big Interview. It markets itself as the end-to-end interview prep platform: mock interviews, behavioral training, video practice, and AI-driven feedback. Sounds great on paper, but here’s the big question: Is Big Interview worth it? As someone who’s burned through more interview prep subscriptions than cups of coffee (and trust me, that…  ( 10 min )

Background Context We’re building Pochi, a full-stack AI teammate that can handle all your coding tasks and think, communicate, and work like a real engineer. One of our recent feature requests involved releasing Parallel agents. Most teams rarely work on a single task at a time. You might be partway through a feature when a bug report arrives, someone needs a small refactor reviewed, or a documentation fix is pending. So you end up switching branches, stashing and popping changes, resetting your workspace, and trying to hold the original task in your head. This is context switching, and it’s one of the biggest hidden costs in software development. Parallel Agents were introduced to remove this cost. They are not new, but the way most tools implement them still felt off. Our own experie…  ( 8 min )

I do not agree with all points in the article: Ben Lesh wanted badly that the Observable becomes a standard in Javascript, once realized that this is not going to take place, some frustration took place Ben Lesh describes Rxjs as: 'Loadash for Events' , which is to my opinion a not deep enough understanding of Rxjs wich is based on Monad, something else than Loadash Ben Lesh took the lead on Rxjs over from Matthew Podwysocki (Microsoft) and did not get the history from where Rxjs is coming from (Haskell, LINQ, Rx.net, Rxjs), which is crucial for a deep understanding of Rxjs  ( 6 min )

I originally posted this post on my blog. "Focus on learning one thing." A coworker told me that every time he got to my desk. At that time, he was the IT/network guy. Years before that, he was a certified Java engineer or something. I was new at this coding thing. I was trying to learn about everything at once. It was back in 2010ish. I was reading The Clean Code, learning Python, using C# at work (coming from Java), and watching PHP presentations in my lunch break. Now you see why my coworker told me to focus. Instead of chasing new and shiny objects (like tools, libraries, and frameworks), juniors (and we all) are better off going deep into fewer tools and concepts. Me 10+ years ago? "Oh there's a new framework. A new C# version. A new CI/CD tool. Hey, what's that new Hangfire thing over there?" Arrggg! Frameworks and libraries come and go. Today it's React with Typescript. And who knows what AI will bring to the table. But chances are we'll be working on a C-type language, still using text files, and writing SQL. That hasn't changed in ~50 years. And it will remain the same. I wouldn't bet all my money though. If you're starting your coding journey, master the topics that have passed the test of time: SQL HTTP C/C++ Data structures Design patterns Vanilla JavaScript Clean code principles Debugging and testing Linux and operating systems (Not all of them at once, of course.) I don't know what other subject to add to that list now. But you get the point. And more importantly than spitting out code, master your soft skills: negotiation and persuasion. Coding is more about collaboration than cracking symbols on a file. It took me quite a while to learn that lesson. And that's why I wrote Street-Smart Coding: 30 Ways to Get Better at Coding. It's the roadmap I wish I had to go from junior to senior. Get your copy of Street-Smart Coding here. Because coding is more than chasing trends. It's about building skills that last.  ( 9 min )

Signal-based forms are one of the coolest new additions to Angular’s ecosystem. Let’s walk through what the sample login form above is doing and why it’s nice to work with. 1. Modeling the form with signals First, we define a simple data model: type LoginData = { email: string; password: string; }; Then we create a signal that holds that model: loginModel = signal({ email: '', password: '', }); This signal is our single source of truth for the form’s state. Instead of separate controls, we bind the whole object and let the form() helper take care of wiring it up. 2. Creating a signal form loginForm = form(this.loginModel, (login) => { required(login.email, { message: 'Email is required' }); email(login.email, { message: 'Enter a valid email address' }); required…  ( 8 min )

Headscale is an open-source server that works like Tailscale's control server. You can run it yourself instead of using Tailscale's hosted service. This gives you full control over your VPN network without device limits or subscription fees. Here's how to set it up and connect your devices. Tailscale is a VPN built on WireGuard. It works like other mesh VPN tools such as Netmaker. Tailscale runs WireGuard in user space, while Netmaker uses kernel-space WireGuard. This means Tailscale has slightly lower performance than kernel-space solutions. But it's still much faster than OpenVPN and easier to use. Here's what makes Tailscale useful: Simple setup: No firewall configuration needed. Easy network setup. Security: Automatic key rotation. End-to-end encryption by default. Ac…  ( 17 min )

Nobody warned me. Nobody prepared me. console.log("hello world"), and my life hasn’t been normal since. So here are the things I really wish someone told me before I became a developer — the unfiltered, sleep-deprived edition. 1. Coding is 10% writing code and 90% “why is this not working?!” You don’t just “build features.” fight with them. 2. Debugging is a lifestyle, not a task You will spend more time debugging than writing code. 3. Tutorials are lies “Let’s build Twitter in 20 minutes!” 4. Breakpoints are your best friend Stop guessing. console.log like confetti. 5. Comments are time capsules from a past version of you who had hope You will find comments like: // TODO: Fix later (lol no) // Don't touch this. It works. I don't know why. Your past self was struggling. Hug them. 6. Big PRs are basically boss-level fights 20-line PR = nice 7. You don’t need to learn everything Stop trying to learn 14 frameworks at once. 8. Don’t memorize anything Syntax? Forget it. Google + Docs = the real full-stack duo. 9. Never touch working code after 6PM You will open one file… Just. Don’t. 10. Imposter syndrome is permanent “You’re not a real developer.” – your brain Final Thoughts Being a developer is chaotic, hilarious, painful, beautiful, frustrating, magical, and slightly traumatic.

As a creative person, I’ve often found myself in a dilemma that many others face—whether to share my ideas or keep them to myself out of fear that they might be stolen, repurposed, or outright stolen. Ideas, to me, are incredibly valuable. They’re the sparks of innovation, the seeds from which amazing things grow. So, the thought of someone taking one of my ideas and turning it into something without me being a part of it has always weighed on me. But over time, I’ve come to understand a truth that’s shifted my perspective: while ideas are important, execution is what really makes them shine.

This isn’t a benchmark post (yet), and it’s not about Docker Desktop’s UI. It’s about how these three approaches actually work under the hood on macOS – and why that makes Docker feel heavy, OrbStack feel light, and Apple containers surprisingly snappy in some workflows.

React has been the foundation of modern frontend development for years, but as applications grow, developers often need tools that go beyond a simple UI library. That’s where Next.js comes in. It builds on top of React and solves some of the framework’s biggest real-world challenges—performance, routing, SEO, and developer experience. In this post, I’ll break down why more React developers are shifting toward Next.js and why it might be the right move for your next project. React doesn’t include a router out of the box—you have to install react-router and configure everything yourself. /pages/index.js → Home No configuration. No boilerplate. Just create files and go. React apps are typically client-side rendered, which isn’t ideal for SEO and can slow down initial page load. SSR (getServerSideProps) SSG (getStaticProps) Incremental Static Regeneration App Router (Server Components) This makes dynamic apps feel faster and more SEO-friendly right out of the box. client-side rendered, which can slow down initial load times and weaken SEO. Next.js provides multiple rendering strategies: SSR (Server-Side Rendering) SSG (Static Site Generation) ISR (Incremental Static Regeneration) React Server Components via App Router This flexibility ensures better performance and significantly improved SEO.

The Ultimate Guide to Autonomous Marketing: How AI, Automation, and Strategy Drive Exponential Growth Introduction: The New Dawn of Marketing Efficiency The strategies outlined in the Test Marketing Book are already being implemented by leading startups to validate new product launches. Learn more → For decades, marketing has been a game of intuition, effort, and often, educated guesswork. We’ve chased trends, optimized campaigns manually, and spent countless hours analyzing data that was often outdated before the coffee got cold. But the rules have changed. We are standing at the precipice of a revolution—a shift from reactive, labor-intensive marketing to proactive, intelligent, and truly autonomous marketing. This isn't just about scheduling social media posts or setting u…  ( 13 min )

Why I Stopped Sending Data to LLMs: Introducing "Zero-Data Transport" Architecture The Problem with "Chat with your Data" Let's be honest: the standard approach to RAG (Retrieval-Augmented Generation) for structured data is broken. You know the drill: User asks a question -> You run a query -> You fetch 500 rows -> You stuff those 500 rows into the LLM context -> You pray it doesn't hallucinate (or go broke on token costs). I realized this wasn't scalable for Enterprise ERPs with huge schemas. So, I decided to flip the script. What if we never sent the data to the AI? I’ve been architecting ADA (Autonomous Data Agent), a system designed to solve the "Context Window" problem using a technique I call Zero-Data Transport. The concept is simple but powerful: treat data context li…  ( 7 min )

I’ve spent the last few months poking at public websites that belong to small U.S. towns, school districts and counties. Not as an attacker, but as the guy who built a small open‑source scanner called CivicMeshFlow. Most of these sites sit on old PHP stacks and very tired CMS installs. Nobody gets promoted for "fixing security headers", and budgets are usually eaten by whatever crisis is happening this month. Still, these sites handle real people’s data. So I started running systematic scans, keeping notes as I went. Very quickly a pattern showed up: different vendors, different designs, but the same security mistakes repeating everywhere. This post is basically my field notes. If you’re responsible for a public‑facing municipal site and only have an hour here and there, this should give y…  ( 10 min )

Honestly, 2025 is already insane enough. Platforms like Character AI and Pollybuzz are absolutely exploding. Millions of people around the world wake up and the first thing they say is “good morning” to their AI girlfriend, then spend three hours before bed doing steamy voice role-play that’s somehow more addictive than actual dating. But give it another five years? That exact same “she” might literally walk through your door, steal the blanket, and roast you for leaving dishes in the sink again. Here’s the comparison literally no one is ready for. Form: Phone, tablet, or at best a tiny holographic figure on your desk. Touch: None whatsoever. You send a heart emoji, your phone vibrates twice, and you both pretend that was her holding your hand. Memory: Perfect. She remembers the name of th…  ( 8 min )

Unlocking Soccer Secrets: AI-Powered Play Analysis from Broadcast Footage \Imagine trying to decipher the complex strategies of a soccer match just by watching the broadcast. It's like trying to understand a symphony by only hearing individual instruments – you miss the overall harmony. Current AI struggles to reliably extract play-by-play data from video, hindering deeper tactical insights. But what if AI could understand the 'why' behind every pass, every tackle, every run? The key lies in combining computer vision with tactical understanding. Imagine a system that not only recognizes player actions but also interprets them within the context of the game's strategic flow. This new approach uses 'tactical priors' – knowledge of common formations, player roles, and strategic patterns – t…  ( 7 min )

Some chapters of Scripture open like a door you walk through. It is quiet. The crowds have gone home. His name is Nicodemus — a Pharisee, a ruler of the Jews, a scholar, an expert, a man respected for his discipline and admired for his mastery of the Law. He knows the Torah. He keeps the traditions. He guards the boundaries. He understands the system, because he is the system. And yet, something inside him is unsettled. Something in him has begun to ache. Something in him has heard the footsteps of God moving through the streets of Judea, and he cannot go to sleep until he understands the voice behind the miracles. So he chooses the one hour no one is watching. He goes at night. Not because he is weak. And there, under the cloak of darkness, Nicodemus meets the Light of the world. The enco…  ( 19 min )

Hi Laravel developers! I've recently created a new package designed to radically speed up your Laravel application development by generating routes, controllers, models, migrations, factories, requests, resources, and tests - all using a single command. Let's generate a complete CRUD API for the Post model: php artisan crud:generate Content/Post \ --template=api \ --fields="title:string,content:text,published_at:datetime,category:belongsTo,comments:hasMany,status:enum:PublishStatus" \ --options="scope:user" The above command generates the following fully functional files: app/Http/Controllers/Api/Content/PostController.php app/Models/Content/Post.php app/Policies/PostPolicy.php app/Http/Requests/Content/StorePostRequest.php app/Http/Requests/Content/UpdatePostRequest.php app/Http/Resources/Content/PostResource.php database/migrations/{timestamp}_create_posts_table.php database/migrations/{timestamp}_create_{pivot}_tables.php (if belongsToMany or morphToMany relationships are present) database/factories/Content/PostFactory.php tests/Feature/Api/Content/PostControllerTest.php API routes automatically added to routes/api.php (will run install:api if the file doesn't exist yet) Laravel Pint run on all generated files 🔗 Package: jcsoriano/laravel-crud-templates Documentation: laravelcrudtemplates.com GitHub: github.com/jcsoriano/laravel-crud-templates  ( 6 min )

organizing app UI i organized the UI of application and then built menu button and slide bar to show user name, existing table and sign out all in one. i have to make policy of UI. button click, input text, font, color, and so on. if there is already some general policy in this field, i'll check it. i built almost the all coding with ai, so don't understand detail, i have to read and comprehend them. in order to make countermeasure at trouble shooting, or expand some function on them. i regard this front and backend code as basement and i wanna develop new application on it. this has basic CRUD function, list page and detail edit page, sidebar for menu.  ( 6 min )
